When the patient has gone, Karl asks Sarah for a word.

The Inner Office

Billy comes in from training and goes off for a shower.

Sarah comes in to tell Karl that his next patient will be late. Things are a bit awkward between them. Sarah apologises for being unprofessional, and Karl apologises for going over the top.

SARAH: Look, I've been giving things a bit of thought, and...I feel awkward here, we both do, Karl!
KARL: No, I don't feel...
SARAH: I just think it's better for both of us if I work somewhere else. I guess what I'm saying is, I want to hand in my resignation.
KARL: Sarah, you don't...

But he is interrupted by the telephone ringing. Sarah answers it - it's Susan. Karl tells her that a barbecue tonight will be fine.

A stranger knocks on the door.

SUSAN: Billy, can you answer that, I'm on the phone! Billy!

Susan opens the door just as the stranger is about to knock again.

STRANGER: Hi! You must be Mrs Kennedy!

Susan looks at his surf board.

SUSAN: Er...yes...
JOEL: I'm Joel. Sorry, I was going to call from the airport, but all the phones were busy.
SUSAN: Er...right...Joel. Are you a friend of Billy's?
JOEL: No, I'm a friend of Mal's. Sorry, isn't Mal Kennedy your son?
SUSAN: Er, yes...but Mal's in England.
JOEL: Oh, I know, yeah, that's where I met him. I guess you haven't got his letter, then?
SUSAN: Er, his letter? Is he alright?
JOEL: Yes, it's just that he said he was going to write and let you know...um, about my staying.

Susan raises her eyebrows.

SUSAN: Staying?! Here?
JOEL: Yeah, that was the idea. He said there'd be no problem. I guess you haven't heard from him, then?

Susan just looks at him(!)

Caitlin is in a bad mood and tells Nick that yes, she's done her history essay and referenced it. She heads off to do some more homework. Nick says that maybe she should ease up a bit on the swimming, as she needs rest too.

Joel is bringing his stuff in and explaining that he's from Tasmania, but was in England to compete in a triathlon competition. She invites him to sit down and have a drink. Apparently Joel hung out with Mal and Catherine in England quite a bit. He offers to find somewhere else to stay - he could call his coach at the Erinsborough Pool. Susan knows his coach (Simon) as he trains Billy too. Susan says it's fine for him to stay with them.

Karl stiffly offers Sarah a lift home, but she's going to meet Kim at the pub. He asks her to reconsider her resignation, and the location of her work is convenient to home and uni for her.

KARL: Sarah...can't we just go back to square one like we were before?
SARAH: Do you need me to explain to you why that's impossible? I was attracted to you so much initially because you were older and more mature...and now I can see you're just like a little boy.
KARL: ...I really don't want you to go.
SARAH: I'll give it some more thought.

Karl invites Sarah and Kim to a family barbecue tonight - perhaps they can try to be friends. Sarah says she'll ask Kim about it.

Susan is typing something on the computer. Karl is making a shopping list. Libby comes out and asks Susan if she can use the computer for her article about the development. Susan moans about the broken computers at the school - they need to raise money quick.

Outside the pool
Joel has spoken to Simon. He's got his list for cross- training and Caitlin isn't on it. Joel tells her awkwardly that Simon said he didn't want Caitlin cross- training...because he thinks she's "got a fair way to go".

CAITLIN: I don't believe this is happening. I'm a loser, and my own coach doesn't even have the guts to tell me.
