Tanaka Apartment
Amy and Leo are going over the Backpackers' bills and Amy tells Leo she can get a better deal on the plumbing for him. David emerges from his room and lets Leo know their mum will be arriving in Erinsborough tomorrow morning. They're determined to finally get some answers about their dad, but David cautions they'll have to tread carefully so their mum doesn't freak out.

Number 22
Sheila groggily wakes up on Terese's couch muttering the name "Brooke!" just as Gary and Terese walk in with breakfast, quietly amused by Sheila's hung-over state. Sheila frantically searches for her phone, worried about a "dream" she had about sending an email.

GARY: Is that all? (smirks) I dreamt I was naked in front of my boss.
TERESE: (whacks Gary's arm) I had a dream that Piper was my mother and she was making me eat pineapple. Go figure that one out?

While Terese talks about her fruitful dream, Sheila locates her phone and is dismayed to learn that she did indeed send an email to Brooke.

Number 26
Amy, Jimmy and Paul are eating breakfast together in the backyard when Sheila arrives home in her dishevelled state. Amy and Paul tease her but Queen Sheila is not amused and heads inside. Paul asks Amy who the bunch of flowers are for on the table, but it's his turn to be unamused when he hears they're for Mama Tanaka.

PAUL: Why are you putting in so much effort?
AMY: It's David and Leo's mum.
PAUL: Yeah the woman who refuses to tell them anything about their father. Sounds like a right piece of work to me.
AMY: Oh look who's talking. She might have a really good reason for that.

The adults send Jimmy inside so they can talk freely. Paul doesn't get why Amy's so keen on impressing Leo's mum and asks what's going on between them. But Amy says her and Leo are just friends.

PAUL: Friends with the man who double-crossed me and made a bet about you? Oh, and then there's his brother, he's just as crafty waltzing around pretending he's the father of Paige's baby. And don't you dare get me started on the mother. It doesn't matter which way you look at it she has been deceiving those boys all their life.
AMY: Don't be so judgemental. Look at our history. Re-connecting with you was one of the best things I could have done for me and Jimmy. I want that for David and Leo too.

Tanaka Apartment
David reminds Leo that he'll be back at lunchtime so he's not to discuss any big topics with their mum before then. Leo says he'll try his best but he can't help stirring up trouble by placing Obaa-chan's Buddha statue on the kitchen table. Leo thinks they should push their mum from the start to get the info they need, but David thinks she needs to be in a good mood to ease her into things. They'll mention Bradley, the blood test and then the Udagawas and see how she reacts. Leo nods and says he'll let Amy know - he invited her along to act as a buffer between him and his mum.

Number 26
Jimmy says bye to Sheila before he heads off to school but Sheila needs some information from him first - basically asking him in a roundabout way how a "hypothetical" someone could delete all traces of an email they didn't mean to send.

JIMMY: You could say you've been hacked?
SHEILA: (unimpressed) That's your solution?

Sheila shoos him off to school before taking a deep breath and making a call to Brooke, getting her voicemail.

SHEILA: Hi Brooke it's Sheila. You're not going to believe this but something terrible has happened... I've been hacked! So that email you got, that wasn't really from me. So I think it's better if you still stay away from Erinsborough for everybody's sake.

Tanaka Apartment
Leo and Amy are on a last minute cleaning spree before Mama Tanaka arrives. Leo fills us in on more of his family tree, which gets more convoluted by the day.

AMY: What about your step-dad?
LEO: We got the name Tanaka from him but not much else. David and I always thought mum was being pragmatic in marrying him. Single mum, two kids, she needed someone for support.
AMY: That is so sad.
LEO: Yeah seems to be a running theme in our family. Mum's mum, Grandma Marcia was the same. Got pregnant to a guy that left her so she married some guy for stability.
AMY: So your mum didn't know who her dad was either?
LEO: No he wasn't around, but he's where the Japanese came from.
AMY: Your family tree seriously confuses me.
LEO: Me too and it's only half of it.

Dear lord. There's a knock at the door - Mama Tanaka has arrived! And immediately tells Leo off for his long hair! Amy introduces herself with a smile as Leo's business partner and says she wanted to be there in person to say how much she admired her sons. "They're wonderful, kind, smart people and that's a credit to you." Leo looks touched by Amy's words.

Cut to later where Leo, Amy and Mrs Tanaka are sitting on the couch in awkward silence. Amy asks about the cruise but Mrs Tanaka just says it was long. She's more concerned in learning why her sons are still living in Erinsborough but Leo says they like it here. Mrs Tanaka also spies the Buddha statue and isn't impressed, calling Obaa-chan a "dragon".

LEO: Obaa-chan didn't like mum or Grandma Marcia. We were from the "wrong" side of the family.
AMY: But she was fond of you boys. Well, mainly David.
LEO: At the end of the day we were still her flesh and blood.
AMY: You don't have to explain anything to me. My family isn't exactly conventional either.
MRS TANAKA: When's David getting here?

Way to read the room, Mama T. Leo looks exasperated but Amy suggests to Mrs Tanaka they go and get a coffee while they wait for David to get home from work. Leo mouths a grateful "thank you" to Amy.

Erinsborough Hospital
David's reading a 'GET HERE NOW' text from Leo while a nurse asks him if he's signed up for one of the training sessions for the new equipment in the spinal unit. While he's jotting down his name he overhears a conversation between Clive and Jasmine and finds out from the nurse about Jasmine's sudden donation made only a few days ago to the spinal unit.

Tanaka Apartment
David tells Leo of his suspicion that Clive is withholding information from them after accepting a bribe from Jasmine. Leo asks if his brother still thinks they should tread carefully with their mum but David looks as though he's beyond that now, evident when Amy and Mrs Tanaka arrive home and he flat out asks, "Who is our father?" Leo says they want to know more about Hiro Udagawa but Mrs T says it's not him. The twins list off all the reasons why they could be related to the Udagawas and tell Mrs T the family is in town now and they should confront them.

MRS TANAKA: You're wrong; Hiro is not your father. When will you drop this?
DAVID: (yelling) We can't, mum! We've been waiting thirty years we deserve to know the truth!

Mama Tanaka doesn't say anything and just walks out of the apartment.

The Waterhole
Sheila isn't impressed that Gary wants to buy chef knives for his new course when they have perfectly good ones at home and refuses to ask the Waterhole's chef what ones he uses. Gary sighs and says that between his mum and Brooke he's not getting anywhere today. Sheila's eyes widen when Gary says he got a bunch of texts from Brooke that morning asking how he was then she suddenly backed off. Sheila grimaces and says she might be a little bit to blame for that before explaining herself.

Terese is having a meeting with Mr Udagawa and says they're struggling a bit at the moment with Jasmine's price war against the Backpackers. Mr Udagawa says he has faith that Terese will persevere then excuses himself when he sees Mrs Tanaka walk in, addressing her as "Kim".

MR UDAGAWA: I didn't know you were in Erinsborough.
KIM: I'm here visiting my sons, but I need to speak to you. Mr Udagawa I need your help - again.

Erinsborough Hospital
Leo and Amy locate Clive and give him an earful about accepting a bribe from Jasmine. Clive says if this is about David's request then he didn't mislead him - he didn't find any information about their father, but Jasmine didn't know that when she made her donation, ergo "win-win".

CLIVE: What I told David was the truth.
AMY: Why should we believe you?
CLIVE: And you are...?
AMY: A friend of David and Leo's. And you know my father, Paul Robinson.
CLIVE: Yes, OK, so I've known Paul a long time and he can vouch for me. I am not lying. Although I'd appreciate it if this didn't get back to Jasmine Udagawa.

Clive walks off and Leo gets a text from his mum asking him to meet her back at the apartment. "Maybe she's finally ready to come clean?"

Lassiter's Complex
Gary's filling Terese in on the whole Brooke/Sheila saga. Gary hopes that Brooke reads between the lines and realises no one wants her back in Erinsborough. He also says there's nothing for Terese to stress about because he'd never go back to Brooke. Terese says it's not Brooke she's worried about it's Sheila - she must really want Terese out of the picture. Gary says that isn't true but Terese can't think of another explanation for her behaviour.

Tanaka Apartment
Kim has brought Mr Udagawa and Jasmine with her to sit with David, Leo and Amy while Mr Udagawa explains that his son Hiro is definitely not the boys' father.

MR UDAGAWA: He was away at the time you were conceived. I have proof. I've just shown it to Jasmine and explained to her. I am quite happy to take DNA tests.
KIM: Mr Udagawa was a family friend. That's why he gave me money when I needed it.
DAVID: But we saw a photo of Hiro. We remember him being around when we were younger.
KIM: Many years after you were conceived Hiro and I did have a relationship.

Leo asks Jasmine why she kept trying to pay them off to stay away from her family but Jasmine was under the same impression that they shared a father and she was just trying to protect her inheritance. Kim thanks the Udagawas for coming and walks Mr Udagawa out with Amy. Jasmine stays back and offers the boys a sincere apology for her actions. She knows they're not related but something tells her they're not getting the full story of what happened with their families all those years ago.

The Waterhole
Sheila literally sprints away from Terese so she doesn't have to talk to her, but Terese is determined to find out why Sheila's being so cold towards her.

TERESE: We both care about Gary. Do you really think I'm that bad for him?
SHEILA: No it's just you can be a little intimidating.
TERESE: And so can you!

Sheila's a bit jealous that everyone listens to Terese, rattling off a story about how when Gary was young he wanted to be a DJ ("Gary Dazzler" lol) so Sheila signed him up for drama classes but he didn't go. But one word from Terese about cooking classes and lo and behold he thinks he's the new Gordon Ramsay. Terese says it's not as easy as it looks.

TERESE: I feel so out of my depth in this relationship. I was with the same man for nearly twenty years and I'm terrified that I'm going to ruin things with Gary. Putting his mum offside would be a good start.
SHEILA: So my approval is important to you?
TERESE: Yes! Of course it is!
SHEILA: (genuine) Oh I am so sorry, Terese. I have been really tough on you.

Tanaka Apartment
Time for conversation #1074565485 of 'Who's the daddy' between the boys and their mum, with Mama T still not backing down. She says she's the only parent they need but David passionately says it's not about her, "We want to understand where we come from!". But Mama T doesn't give in and tells her sons just to be happy with what they already have before walking out of the apartment. Amy follows after Mrs T, hoping she might be able to talk some sense into her. In a fit of frustration, Leo picks up the Buddha statue and smashes it on the ground. The boys are surprised to find a key with a wooden keychain attached inside.

The Waterhole
Mrs T tells Amy it was nice of her to check in on her but she'll be OK. Amy says that she knows how the boys feel because she grew up without a dad too. Mrs T thinks this is a great time to ask Amy to have a chat with her sons and tell them it's OK not to know their father, but Amy is like 'um how about no?'. Amy sees Paul walk in with Jimmy and points them out to Mrs T, who looks concerned at the sight of one Paul Robinson and the fact that he's Amy's dad.

AMY: I think you need to reconsider you stance with Leo and David. It might seem like a bad idea but if you just let them meet their dad, find out...
KIM: Enough! I'm sick of everyone pushing for this! Keep out of it and stay away from my sons.
