Number 24
Paul and Hannah ask Harold if he is only allergic to dogs, or if he's allergic to other animals. Harold isn't really paying attention and keeps changing the subject to what they're having for dinner tonight. Hannah suggests that Harold might not be allergic to some pets, like turtles, but Paul doesn't want a turtle, he wants something small and furry. Harold says Paul could always go to Hannah's to play with the dog, but this house has to remain an animal free zone.

After Harold leaves, Paul takes a guinea pig, Axel, out of his bag. Paul thinks that Harold's allergy is just in his mind, so what he doesn't know won't hurt him.

Number 32
Caitlin tells Billy it's probably her fault for telling Anne they were in the nude. Sarah rushes into the kitchen saying 'you were in the what?!' Caitlin says it isn't how it sounds. Sarah says good and rushes off. Billy tells Caitlin that Anne can't handle him being friends with other girls, and if she doesn't believe him then that's her problem. Caitlin thinks they always make up but Billy thinks this time is different. He isn't even sure he wants to make it up with her.

Number 24
Hannah sneaks in carrying a cage she borrowed from Toadie. She didn't tell him what she needed it for as it would be all over Ramsay Street in about 10 seconds. Paul explains that he didn't buy Axel, Mickey Dalton was just giving him away and no one else wanted him. Paul plans to keep Axel out of sight long enough to prove Harold isn't allergic to him. They hear Harold leaving the shower and Paul rushes to hide Axel while Hannah starts chopping vegetables. When Paul returns from the other room, Harold starts sneezing, assuming it's some pollen from the garden.

Number 28
Sarah arrives for a study session with Karl. Karl has dinner almost ready and Sarah starts to question him on how many babies he's delivered over the years. Karl lost count, but he never gets sick of it, he's an old softie when it comes to babies. Karl brings her a book about babies that Susan used when she was pregnant. Sarah hopes she isn't being a nuisance and doesn't want to take up his time if he's got things to do.

KARL: A major nuisance. I can't tell you how much I was looking forward to scraping the mildew off my stamp collection tonight.

Number 32
Anne returns home late, explaining to Ruth that she was out walking and lost track of time. She tells Ruth that she and Billy had another fight about Caitlin. They keep doing things together which aren't friend things and Anne can't help getting jealous. Anne knows Ruth will say that they're just kids, he's her first real boyfriend and she'll have heaps before she settles down, but what if they are the exception and they're meant to be together. Ruth says people that argue all the time might not be meant for each other. Anne thinks people that don't love each other have nothing to argue about. She loves Billy and she wants to sort out this problem if it isn't too late.

There is knocking at the door and Ruth checks with Anne if she'd want to talk to Billy if it is him. Ruth answers the door and lets Billy in, taking Bonnie for a walk to give them some peace. Billy tells Anne that now they've calmed down, they need to sort things out once and for all.

Number 24
As Paul, Harold and Hannah are making dinner, Axel crawls through the kitchen and Harold starts sneezing again. Harold thinks he must have pollen on his vest so leaves to change. Paul rushes to the bedroom to sneak Axel out of the house. He then rushes back and whispers to Hannah that Axel is gone, he must have got out. They have to find Axel before Harold sees him.

Number 32
Billy explains that there was nothing to the skinny dipping, and thinks Anne is just jealous because it was with Caitlin. Anne says Billy would feel the same if it was her and another boy but Billy claims he'd be fine with it if she said it didn't mean anything.

BILLY: If we can't trust each other I don't see a future for us.
ANNE: I do trust you.
BILLY: That's not the way it seems. I'd really like us to still be friends you know, but as for the rest of it, it's not working. And it's better to call it off now then to let it drag on and make each other miserable. Let's face it, we're growing up and changing, we're moving in different directions, it's normal.
ANNE: I thought we loved each other.
BILLY: We did and I'll always love you as a friend but I've accepted that it's time to move on and I think you should too.
ANNE: So that's it then?
BILLY: Yeah. I guess I'll see you around.

Anne holds it together long enough for Billy to leave and then starts crying.

Number 24
Harold returns to find Hannah and Paul crawling around the living room, Hannah claims she was looking for her hair elastic. Hannah spots Axel in the kitchen. Paul rushes to get Axel while Hannah tries to distract Harold. Harold starts sneezing again and rushes to get some tissues from the laundry. While Harold's back is turned, Paul manages to put a box over Axel, but the box starts moving away across the floor. They chase after the box, only to find it upturned and Axel is missing again!

Number 28
While drinking wine over dinner, Sarah asks Karl how he manages to remember everything. He didn't have much of a social life. Karl says that Sarah's done a lot of hard work and she should be proud of what she achieved. Billy returns home and goes straight to his room, telling Karl he isn't hungry.

Number 24
Harold, Paul and Hannah finish dinner. Harold and Hannah tidy up, while Paul spots Axel and races towards him again, putting the box over him. Harold sees the box and demands that they show him what is inside. They hear Axel squeaking, so Paul reveals the guinea pig. Hannah and Paul argue over whether to call the guinea pig Axel or Alex, as Harold sneezes.

Number 30
Anne arrives to see Caitlin and hear her version of what happened. Caitlin tells her that they went skinny dipping in the pool on a dare, but she isn't interested in Billy and they are just friends. Anne thanks her, she had to hear it from her. Caitlin says she and Billy need to just talk things over. Anne tells her that they broke up and this time it's for good.

Number 24
Harold tells Paul to take Axel to a pet shop, but they won't take him as he's too old.

HAROLD: You two are missing the point. You know about my allergy to fur, and you bring a furred animal into the house and then you try to deceive me.
PAUL: He's only a little guinea pig, I think you're so cruel.
HAROLD: And I think you're thoughtless and irresponsible.

Harold says the animal can stay where he is, but only for the time being until other arrangements have been worked out. Harold starts sneezing again and leaves. Paul and Hannah think other people have allergies and don't carry on like Harold, they take a pill and forget about it.

Number 28
Karl clears up dessert.

SARAH: What can I say? Thanks for helping me study, thanks for the meal and thanks for making me laugh.
KARL: Yes, my cooking often gets that reaction.

Karl says it was a pleasure and he enjoyed the company. Sarah asks if he'll be around tomorrow if she has further questions. Karl asks her if she's studying day and night, when will they practise golf. She suggests tomorrow before work.

KARL: As long as you promise not to clock me with a 4 iron, I'm particularly fragile at that time of the day.
SARAH: Oh but now you're taking all the fun out of it. I'll try and restrain myself.
KARL: Okay, it's a date.

Karl puts his hand on Sarah's shoulder and they stop for a moment, looking longingly at each other. They are interrupted by the phone ringing. Karl goes to answer the phone, it's Susan. He explains to Susan that Sarah is leaving and asks if she's got everything organised. Susan talks about how great her work have been about it, while Karl clearly is feeling rattled after that moment with Sarah.

Number 30
Bob races to the door and starts barking. Sarah returns home and picks Bob up, before going into the kitchen. She says hi to Caitlin and Anne, who realises how late it is and should probably go home. Caitlin assures Anne that Billy probably didn't mean it when he broke up with her. Anne thanks her, but he did.

Number 28
On the phone, Susan asks Karl how his evening was. He explains he was helping Sarah study about midwifery.

SUSAN: You're telling her about the birds and the bees, now honestly I better get home quick smart, given how easily you find alternative female companionship.
KARL: Well much as I don't mind helping Sarah with her study, I would have jumped at a better offer, such as having a romantic dinner with my wife such as was originally planned.

Susan says she's going to take the rest of the week off so she'll be back tomorrow. Karl says he and Sarah have a bit of golf in the morning but then he'll be all hers.

SUSAN: Well if you can pencil me in to your busy social calendar.
KARL: Susan, that's uncalled for!
SUSAN: It's a joke darling.
KARL: Yeah well fair enough, it wasn't a very good one.

Susan asks if everything is alright. He says now she's coming home, everything is perfect.

Number 24 Back Yard
Paul is looking for Axel but he's gone again.

Number 28
Karl is heading out to golf. He passes Catlin who tells Billy that Anne came to see her. Caitlin says Anne has the right not to trust them as they weren't always just friends. Billy says that Anne should believe him, and he's told her over and over. Caitlin says she'd have felt the same way as Anne and so would most people. Caitlin doesn't know why Billy is being so hard on Anne.

CAITLIN: What about when she did that photo work with James? If you found a photo of them nude together, are you telling me that you wouldn't be jealous?
BILLY: Well if she told me that it didn't mean anything I would have believed her.
CAITLIN: Well it must be nice being you. The rest of us have to get by being human.

Surgery
Susan arrives. Sarah is surprised to see Susan here early, Susan says she left before the sparrows. She goes in to see Karl who is delighted to see her back so soon. Susan asks if they can have the romantic dinner tonight. Karl says he's already organised to help Sarah with her study.

SUSAN (jokingly): Honestly Karl, you play golf with her in the morning, you come and spend all day at work with her and then you help her study at night. If I didn't know better I'd say you were having an affair.
