Susan tells Lyn that she wants to work things out with Karl, but she thinks he wants a divorce
Joe and Lyn start to record their renovation show audition video.
Boyd sees Gus standing at the end of Ramsay Street, but when he turns back, he's gone.
Summer has got her kite stuck in a tree and Gus offers to help her with it. He climbs up.
Karl says that it's a bit of a challenge getting used to a single bed. Susan offers to iron his shirt for him while he has a shower. Things are pretty awkward between them.
Gus has retrieved the kite and is talking to Summer when Izzy sees them. Izzy thanks Gus, but says that Summer knows better than to talk to strange men in the park. She seems quite impressed with Gus though. She tells Summer that they should have got his name!
Susan invites Karl for lunch and talks about cooking curry tonight. Karl says he probably won't be there. Things are still extremely strained.
Someone is playing back Joe and Lyn's "Making Mansions" audition video. After the main video, the camera is left running while the family argue. The person pauses the tape thoughtfully.
Karl is looking for his diary and Susan finds it. He heads off to "heal the sick". When he leaves, Susan puts her head in her hands.
Gus comes in and sees Izzy at a table. She invites him to join her for a drink. At that moment, Max catches sight of Gus.
MAX: Gus Cleary! TGus-buster! Bloody hell! Who'd have thought, eh?
Max shakes hands with Gus and introduces Izzy properly. They banter amicably. Apparently Max and Gus worked together on the oil rigs. He said he was surprised to hear that Max had left rig life to run a pub and he had to come to see for himself! Max tells Gus that he's really happy in Erinsborough.
When Max has gone to get the drinks, Izzy says that Gus can tell her all the gory details about Max on the rigs!
Later at The Pub
Max and Gus are playing pool and Gus is telling Izzy how Max was a heart-breaker when they were on leave. Max says that Gus is ruining his reputation! Izzy invites Gus to dinner at the Hoyland House that evening and gives him the address. She flirts with him shamelessly.
Susan cuddles Audrey who is still wearing the collar. Karl comes in and things get awkward straightaway. Susan says she could make him some food up but Karl says he'd better get back to the surgery.
Suddenly they hug and then they kiss quite passionately. Then they apologise to each other and agree it's a difficult situation. Karl rushes off to the surgery leaving Susan to smile happily.
A Building Site
Joe is instructing Jack in doing window seals. They are getting on well.
Izzy brings Karl a cup of coffee. He is very pleased and says she's a mindreader. Izzy says that she heard one of her customers saying that Karl was working through his lunch-hour today.
Izzy asks Karl if he's pining for his dream of tropical warzone medicine, and Karl says he thinks he's past that. However, things are complicated enough - he and Susan kissed earlier. Izzy says she thought they were just housemates, but Karl says it's difficult to deny the history between them. He doesn't want to give her false hope, but Izzy says just living under the same roof as Susan is giving her false hope.
Izzy suggests that Karl moves out, but it's not that easy - it's still his family home and he's not willing to give up on his family. Izzy says that maybe he should give things another shot with Susan then.
KARL: No, no, no. This is the toughest decision of my life, but I know it's the right one. No, Susan and I are finished. Our marriage is definitely over.
Izzy is silent at this proclamation. Presently, Karl, shakes off the melancholy and asks her what she's up to. Izzy tells him that she's got a hot date tonight!
The Building Site
The person who viewed the Scully's audition video is now filming Joe and Jack from a distance.
MYSTERY PERSON: All seems peaceful now, but beneath the apparent calm of father and son working contentedly together lies a hotbed of disagreement.
At that moment, Joe and Jack get into an argument about the building trade.
MYSTERY PERSON: The cracks are beginning to show. If they argue like this at work, what's it going to be like when their home becomes a worksite?
Joe and Jack make up.
MYSTERY PERSON: Or maybe it'll be the most boring television you've ever seen! I thought these two were meant to argue?!
Karl says that Izzy's date sounds promising, even though it's not really a date, it's just dinner with her family. Izzy says to give her time!
As she leaves, Izzy tells Karl to take care of himself. Karl says it's probably best that they don't meet up at the surgery anymore as people might get the wrong idea. As Karl shows Izzy out, Lyn is next in the waiting room. She does not look at all happy to see Izzy there.
Susan comes round to see Lyn about the book club meeting. Lyn sits her down for some "girl talk". Susan blurts out that Karl kissed her and she thinks he really regrets his decision. Lyn isn't so sure - Karl didn't actually say something. Susan says she's certain that Karl is coming back to her, even if it does take some time. She's overjoyed, but Lyn does not look convinced.
Gus admires Max's house and Max tells him that the house is up for auction. Izzy serves up some nibbles and Gus flirts with her.
Steph comes in and is excited that there was a bike in the driveway. She's impressed with Gus's taste in bikes and Max introduces her to Gus.
Later at the Hoylands
After dinner, Gus is still flirting with Izzy. Max sends Summer off to bed and Gus offers to meet her again to fly her kite.
Later, Gus tells stories about the rigs. He refers to Max as "The Killer". Gus is off the rigs too now, and staying with his father. He says he's not too bothered about settling down.
Gus tells them that Max took his job as Safety Supervisor very seriously.
Even later at the Hoylands
Gus is offering to give Steph a spin on his bike. Max goes off to his shift at the pub.
When he's gone, Steph asks why Gus calls Max "The Killer". He says it's short for "Ladykiller" and Steph looks a bit takenaback. Gus says that none of Max's women were as good as her!
Still later at the Hoylands
Steph says goodnight, leaving Gus and Izzy on their own.
IZZY: So. Then there were two.
GUS: I think we might be two of a kind, Izzy. What do you think?
IZZY: I think you might be right!
Gus invites himself to stay for another coffee.
The next morning at The Hoylands
Gus is asleep on the sofa, much to Max's surprise. He mutters that Gus hasn't changed(!)
Izzy asks if he can use one of the rooms at the pub, and Max says that should be OK.
When the camera turns on Gus, we see that he isn't asleep after all.
Lyn sees Izzy while out walking Oscar. Izzy asks her to let her know if there's anything she can do to help Susan and Karl through their problems.
LYN: I think you've done enough, don't you, Izzy?
Lyn goes on that she's seen Izzy hovering around Karl and she thinks it's indecent. Her voice becomes loud enough for half the street to hear. Lyn continues that Susan and Karl were perfectly happy before Izzy came along and she can keep her false sympathy to herself.
LYN: Stay away from them, will you? You've done enough damage.
