Eden Hills University - Girls' Bathroom
Susan hears her phone ringing on the bathroom floor where she threw it. Taking a deep breath she exits the stall and picks it up, relieved to see that it's Zeke. But before Susan can answer she hears footsteps and quickly rushes back into the stall. Panicking, she stands on top of the toilet when the footsteps get closer. Dialling Zeke's number she whispers into the phone that she needs him right now.

Zeke races through the halls and into bathroom where he sees Susan's classmate, Gemma, standing in front of Susan's stall. Zeke coaxes Susan out and Gemma says she came to check on her because she was worried. Susan claims that Gemma tried to force the door open, but Gemma says she was worried Susan might have fainted. Zeke carefully guides Susan outside so he can take her home, clearly worried by how agitated she is.

Number 28
Karl, Libby and Zeke sit with Susan on the couch, afraid to take their eyes off her. Susan knows they're worried but treating her like an invalid isn't helping. She says she just overreacted at uni and that she'll be fine. When Susan goes into the bedroom, Karl says he's going to call the police and report Gemma. Zeke doesn't think she's the culprit - her concern was pretty genuine - but Karl wants to keep the police informed about everything.

Harold's Store
Sophie's down in the dumps because she got a D on her geometry test. Callum doesn't think it's a big deal, but Sophie hates not understanding things. She always asked Harry for help when it came to maths, but now she can't. Callum sees "Mike" and calls him over for advice. Sophie's mortified, but Callum ignores her and asks if someone should just give up hope if they fail a maths test. Thinking Callum is talking about himself, Michael says that tutoring can be a big help. When he leaves, Sophie says she can't afford tutoring and can't admit to Mike that she's bad at something.

SOPHIE: I've read about this. I think I'm having an existential crisis.
CALLUM: A what?
SOPHIE: Forget it.

Number 24
Sophie is sitting at the kitchen table with her maths books and a big pile of screwed up papers with aborted geometry homework on them. Callum drags Andrew in and announces that he's Sophie's new tutor. Sophie is less than impressed.

ANDREW: You're still angry with me about the whole Harry thing.
SOPHIE: You were a jerk.
ANDREW: You know, I miss him too.
SOPHIE: Why, because you don't have anyone else to pick on?

As it turns out, though, Andrew isn't all that helpful. He's more of a profit sheet or balance statement kind of guy - he copied all of his geometry homework off Harry. Sophie dismisses him but Callum makes Andrew promise to find her a tutor.

Number 28
Libby has asked Lyn and Terry to pop around for a visit. Karl isn't happy with the visitors and says that Susan needs some alone time, but Susan appears from the bedroom and says she can make up her own mind. She claims her anxiety "is just a state of mind" and she'll get over it. Putting on a brave front, she tells Lyn and Terry she'd love to join them at Harold's for coffee and a chat, much to Karl's displeasure.

Harold's Store
Terry and Lyn are regaling Susan with tales from their rock climbing adventure when Terry goes off to make them some tea. Lyn says it's nice to see Susan out of the house but wants to know how her friend really is. Susan admits she's not great and Lyn tells her it will get better. Terry has a crisis in the kitchen and Lyn is reluctant to leave Susan alone, but she says she'll be OK. However, it doesn't take long for Susan's agitation to come back, especially when Gemma walks into the shop. Gemma asks how Susan is, but Susan just timidly orders her to stay away before running out of the store.

First Commercial Break

Harold's Store
Lyn and Terry apologise to Karl - they only left Susan alone for thirty seconds max. Karl's worried because Susan left her purse and all her belongings behind. Lyn says they've looked all over Lassiter's, but Karl says he's going to look around the lake and community gardens. Lyn says she'll take the carpark and Terry offers to stay in the shop in case she returns.

Blokes Club HQ
Karl and Lyn's voices are heard calling out for Susan over stock shots of Lassiter's locations until Karl finally finds her in the blokes shed. Karl's relieved and sits down with her on the steps. He asks if she's ready to go home, but Susan shows him her shaky hand and he gently takes hold of it.

SUSAN: I was too scared to try and walk. What if it's a relapse?
KARL: We'll just sit here for a while.

He kisses her on the forehead and says it'll be alright.

Charlie's Bar
Natasha is beating Andrew, Summer and Chris at pool while Andrew is asking Summer to be Sophie's maths tutor. Andrew reckons Summer's "the biggest maths brain I know", but Summer smirks Natasha's way and says that may not be true. The boys want to know how Natasha won and Summer says it has to do with angles, but Natasha ignores her and says they have to fulfil their bet - trousers off and once around the table.

Lassiter's Complex
Summer leaves the boys in the bar and finds Natasha outside. She asks when Natasha's going to tell Andrew the truth about being a maths brainiac. Summer thinks it's dumb that Natasha believes being smart is a turn- off for boys. But Natasha's all, "I've got brains and I'm hot", and thinks Summer should just mind her own business. Sighing, Summer walks off and runs into Lyn, who is on her way to take some coffee and cake to Susan.

Number 24
Natasha lets herself in and announces to Sophie and Callum that she's there to help them with maths. The kids are dubious until Natasha shows them a geometry trick to help calculate angles. Sophie accepts her as her tutor but wants to keep the arrangement quiet, which suits Natasha to a T. Andrew walks in and is confused to see his girlfriend there until Sophie blurts out that Natasha's a maths genius. Andrew looks as though he doesn't quite believe it.

Second Commercial Break

Number 24
Natasha's worried about what Andrew's going to say but it turns out he's quite pleased to have such a brainy girlfriend - and a hot one at that. They start to kiss and Sophie and Callum throw paper at them.

Number 28
Karl and Lyn managed to convince Susan to return home, but things are still a bit terse between Karl and Lyn so Lyn decides to go home. Karl wants to know if he can call the neurologist for Susan so they know what they're facing. Susan's reluctant at first in case the MS has returned, but then she reasons that it could just be panic attacks. She tells Karl to make the call.

Harold's Store
Natasha is doing some more tutoring with Sophie and Callum while Andrew proudly looks on. Summer and Chris walk in and Summer's surprised that Natasha's secret is out in the open. Natasha snarks that she can help Summer out with maths if she needs it, but Summer ignores her and tells Sophie to give her a call if she needs help with any other subject. Michael walks in and Chris tells him how impressive Natasha's maths skills are. Michael smiles and says his daughter is smart - but amends this statement when he sees her snuggled up to Andrew. "Smart at most things..."

Number 28
Libby and Zeke help Karl set the table and ask if there's any word from the neurologist, but Karl says he's not expecting to hear back till tomorrow. Zeke answers a knock at the door and invites the cops in, who are returning Susan's laptop after scanning it for evidence. When Constable Page says they didn't find anything, Karl gets frustrated.

KARL: So what do we do now? Wait for Susan to get run down or something? Or a brick to come through the window? Maybe the house to get set on fire, because goodness knows they know where we live.
LIBBY: Dad...
KARL: Look, what aren't you getting here? My wife might be seriously ill, and if she is it's not helped by your incompetence. Now how does that make you feel?
CONSTABLE PAGE: Yelling at me won't help, Doctor Kennedy.

Susan watches them silently from the couch.

Third Commercial Break

Number 28
Libby finds Zeke sitting in the lounge room, unable to sleep. They're worried about both Susan and Karl now. Zeke thinks they must have overlooked an vital clue - he doesn't know what, but he knows where to start. When he grabs Susan's laptop Libby reminds him that the cops have been through it, but Zeke says they haven't hacked the uni records. Libby doesn't think Zeke should be doing any hacking considering he's on a good behaviour bond, but Zeke says he can't just stand by and watch Susan suffer anymore.
