Erinsborough High School
Brennan turns up with flowers for Kate after school, who notes that it's not even her birthday yet - raising immediate suspicion in viewers' minds that said birthday has been casually shunted from its traditional date in February for reasons of plot convenience. Brennan suggests they go back to his place, but Kate needs to go to the penthouse first to pick up some clothes.

BRENNAN: You're not gonna need any clothes for what I've got in mind!
KATE: Mark, we're at school.
BRENNAN: Oh. Sorry, Miss Ramsay.

They kiss, and she promises to be at his house in half an hour. Susan appears for a good pry, and Kate gushes about how amazingly well things are going with Brennan.

KATE: You know, he really is the love of my life.

Susan expresses how happy she is for Kate, then heads off to pick up Karl from the airport, following his trip to the UK.

No 28
Susan and Karl come in, Karl wearing a rather curious hat. She is filling him in on Lauren and Brad's disappointment over Lisa not being their daughter.

SUSAN: Are you going to take that hat off?
KARL: No, no, no. I like it.
SUSAN: It looks pretty stupid.

Karl says Holly gave it to him, and Susan backpedals, saying it's sweet. Karl presents her with his gifts from the UK: a kiss from Malcolm, a kiss from Zeke, and some earrings from Rachel. Karl has also 'bought' her a present himself: a selection of freebie hotel toiletries!
SUSAN: I don't know what to say (!)
KARL: You're welcome!

Susan leaves for a staff meeting, but the moment she's out of the door, Karl removes his hat, and admires his reflection in the kettle - he's dyed his hair black!

KARL: You handsome devil!

No 32
The Willises and Turners are still upset about Lisa, and Terese express hopes that her biological parents will be better than the ones she was lumped with. Lauren is very upset, and Matt tells her to think of Lisa's adoption experience as the exception, not the norm. He also says they should proceed with caution from now on, and not get involved with potential daughters until they're certain. The plan is now to go back to hiring a private investigator.

Harold's Store
Josh, Imogen, Amber and Bailey are all depressed about learning that Lisa isn't their sister - even sceptic Josh admits she was 'way cooler' than he anticipated, while Bailey's feeling bad about having found her in the first place. Josh gets out his laptop and starts doing, confirming he's decided to retake the whole of Year 11: he says Lisa got him thinking, and he's decided to stop feeling sorry for himself and get on with it. He gets up to buy himself another coffee first.

AMBER: Hey, Mr Self-Absorbed. Are you going to offer anyone else one?

Josh sheepishly offers to get a round of drinks in, and while he's ordering, Imogen congratulates Amber for her newfound assertiveness.

Lassiter's
Paul stops Kate outside the hotel, and suggests they go out for dinner tonight to discuss the forthcoming renovations at Charlie's, and to give Kate an early birthday treat. But as they enter the building, Kate gives Paul the brush-off, as she's still annoyed about his attitude towards her relationship with Brennan. Paul defends himself, saying he doesn't want Kate to get hurt. But she insists she won't, and tells Paul that she doesn't know if she can see him until he accepts Brennan.

No 28
Susan is back from her meeting, and is shocked and amused by Karl's new look!

SUSAN: Did you let Holly loose on your hair?!

She promises to contact the hairdresser and arrange an appointment to sort it out - but Karl is not amused. He says he did it on purpose, and that he knew Susan would be negative.

SUSAN: How can I be positive? You look like a caricature!

She's further appalled when she learns that it was a self-dye-job.

KARL: Susan, this cost five pounds! That's over nine dollars our way, and it's worth every cent too.

Susan wonders if something happened in England to bring this on, but Karl resents this suggestion, and strops off to have a shower. As he walks away she notices that he's missed a big patch of grey on the back of his head - but opts not to say anything!

Harold's Store
Paul runs into Brennan, who's trying his best to be conciliatory - he explains he's organising some birthday drinks for Kate at 'our' place tomorrow, and wants Paul to come along.

PAUL: Oh, our place? She's moved, has she?
BRENNAN: It was just a slip of the tongue.

Paul makes it clear he's not interested in coming along, despite Brennan's best attempts to talk him round, saying Kate still loves Paul, whatever he thinks of him. Paul accuses him of organising a 'lame' celebration and says Kate deserves better, but Brennan says Kate wanted it low-key - and reiterates that he hopes Paul can make it, before leaving.

Charlie's
Paul is doing what he does best: throwing money at a relationship problem in the hope that it will go away. He is ordering Terese to arrange a lavish surprise birthday party for Kate at Charlie's, no expense spared, an hour before Brennan's own gathering at No 24. Terese says it's very short notice but Paul insists, and she promises to pull something together. But she also asks Paul whether what he's doing has anything to do with his antipathy towards Brennan. Paul admits Kate needs to be reminded how much Paul cares for her - which is why it needs to be 'the party of Kate's life'.

Lassiter's Complex
Outside the hotel, Terese is talking to Kate about her birthday; she's told Brennan she doesn't want a present. Terese points out that this is crazy, since they're at the 'honeymoon' point in their relationship when guys are at their most generous. Terese recalls the jewellery Brad lavished her with at the start of their romance, saying each piece carries a special memory. She asks about the locket Kate's wearing (the one belonging to her grandmother Anne, that Paul gave to her as a family heirloom). Kate says that she hasn't worn it for ages, but admits that family's on her mind at the moment given her fallout with Paul.

TERESE: See? Objects have memories. Don't knock them back. Because one day down the line it's all going to be about bills and mortgages and scheduled date nights. So you should make the most of it while you can.

Kate admits she's enjoying spending time with Mark without dwelling on the future.

Harold's Store
Lauren gives Amber some money for a dress, for her photography internship. But Amber admits she's decided she doesn't need one, after Lisa commented on not being able to go shopping as she was short on money. It's made Amber realise she already has so much. Lauren looks sad, and Amber apologises for bringing up Lisa - but Lauren says she's fine, and Amber leaves. Bailey, who has been earwigging, tells Lauren he can see she's not fine, and that it's his fault for contacting Lisa. But Lauren tells him he went out of his way to help his mum, which proves how lucky she is to have him. Lauren tells him it's not his fault, and to just worry about being a kid.

BAILEY: That's what Lisa said.
LAUREN: Well, she was right about that too, wasn't she.

Bailey leaves, and Lauren looks sad again.

Charlie's
Paul on the phone, arranging a flight for an unknown female whom he 'needs here in plenty of time'. When he's done, he chats to Susan and Karl at the bar, quietly bemused by Karl's hair! He invites them to Kate's birthday bash here tomorrow, and Susan says Brennan has already invited them to No 24 - but Paul makes out that Brennan's drinks have been replaced by the party at Charlie's. They promise to come along.

PAUL: And by the way, whatever you've had done to your hair, I'd demand your money back. And they missed a bit at the back as well.

Susan sniggers, and Karl demands to know why she didn't tell him. Terese walks by, saying Karl's looking good.

SUSAN: You know she's just being polite.
KARL: Is it so inconceivable another woman would pay me a compliment?
SUSAN: Honestly? Yes it is! Karl, it looks ridiculous. And if this is another mid-life crisis I'm telling you now, I won't be having it.

Paul, overhearing, sniggers to himself at his table. But Karl is offended by Susan's words, saying he knows he's a silly old fool, and stomps off towards the exit. She runs after him, saying she was just teasing.

No 28
Susan apologises to Karl for going overboard with the teasing about his hair, but asks why he's taken it to heart all of a sudden. Karl admits what prompted him to dye his hair: while he was in England, a fellow parent in the park mistook him for Holly's grandfather. This just makes Susan laugh even more.

KARL: I guess you're right; I'm just a ridiculous old man.
SUSAN: Well - with that hair, maybe just a little bit. Oh, Karl - come on. You know I love you, grey hair and all. I think you're gorgeous and sexy.

She kisses him.

SUSAN: Come with me.
KARL: Blue box?
SUSAN (pointing to his hair): Oh, first things first! No, I think I might have something we can get that out with. Come on, Grandad.

Ramsay Street
Brennan and Kate pull up outside No 24. She moans that Paul is still being stubborn about their relationship, and Brennan says it's just his way of showing he cares.

KATE: Yeah, that's a polite way of putting it. To me, it feels like he has this pathological need to control me, which is just going to make me single and unhappy like he is.

Brennan says Paul just needs time. He tells Kate to go inside and have a cuppa, while he goes and takes care of a few errands. Kate suspects it's about her birthday, but Brennan's acting all innocent. Kate reminds him she doesn't need a fuss. She's just happy they're back together.

KATE: Honestly, I couldn't be any happier than what I am right now.
BRENNAN: Oh, we'll see about that.

Charlie's
Brennan is buying a bottle of something when he runs into Paul. Brennan says he's heard about Paul's surprise party for Kate via Toadie. Paul says Brennan's invited as well, and adds that a very special guest will be attending. Brennan's very gregarious about this attempt to upstage his own bash, and says he's sure Kate will love it. Paul is a little disappointed that he's not annoyed, but Brennan says it's not a competition - he wants them to get along. For his part, Paul says he'll make sure Kate gets to Brennan's bash if he still wants to have a separate one. But Brennan says he'll be at the Charlie's party, and will also keep Kate distracted so she doesn't suspect a thing.

As Brennan leaves, Terese stops him and asks if he wants any suggestions for Kate's birthday present - but he confirms he's ignoring Kate's request not to get her anything, and has already got a present sorted. Meanwhile, Brad is surprised to see Josh reading a school book, and is impressed at his commitment. Brad tells Terese that it was Lisa who convinced him to return to school.

TERESE: I know. Hey - I wish she'd been your daughter too.

No 32
Lauren is still sad, and Matt tries to cheer her up - saying her daughter's still out there, and they just need to pick themselves up and start again.

LAUREN: We won't find her.
MATT: Yes, we will. Sure, it's not gonna be easy, and it might take months or years. But we will find her.
LAUREN: No we won't. Because I'm not gonna look for her again.
MATT: You don't mean that.
LAUREN: Yeah, I do.

Lauren explains she can't bear the thought of going through what they went through with Lisa repeatedly. She tells him not to call the private investigator; the search is off, and Brad and Terese will have to accept that, because she can't go through this again.

Charlie's
Paul is instructing an underling as regards the decorations for Kate's party, when Susan comes in looking outraged.

SUSAN: I just ran into Brennan outside.
PAUL: Well lucky you (!)

Susan wants to know why Paul tried to upstage Brennan's own party. He says he loves Kate and wants her to have the best, and is doubtful when Susan says Mark loves her too. Paul says he's broken Kate's heart too many times, and he won't let it happen again.

SUSAN: Kate is the happiest I have ever seen her.
PAUL: For how long, though?
SUSAN: Paul, she's head over heels. Just let her enjoy it!

Paul says he's the only person Kate can really count on, and that Brennan will only leave her again.

No 24
We see Brennan putting a bottle of champagne in the fridge, and opening a jewellery box. He smiles as he looks at the ring he's bought for Kate...
