Izzy announcing her engagement, Susan overhearing. Darcy tripping down the stairs. Mac breaking down in the Coffee Shop. Izzy stuffing her jewellery into Darcy's pockets.
Karl and Izzy's Flat
A flustered Izzy hurriedly knocks items over and removes the kitchen window to create the illusion of a burglary.
Connor is practicing his best bartender cocktail swinging tricks when the doors suddenly blast open. Looking around, he notices a robot on the ground and it tells him that if he dares, a robot annihilation challenge is to be held against the opposing pub. With a determined look on his face, Connor shows the robot where to go and shouts out to Seamus that he's ready for war.
With a plate of sprinkled donuts by her side, Mac informs the person on her mobile that she is no longer interested in any dodgy dealings. Stu joins her and she apologises for being distracted for the past few weeks, but she is turning over a new leaf. Stu jokes around, saying that he could always slap her back into line and knows she would do the same thing for her. She says he's like Forrest Gump.
MAC: You know, you're kinda like Forrest Gump.
STU: What, dimwitted and naïve?
MAC: Mmhmm. And very loyal, determined to see the best in people.
Izzy wanders in and doesn't hear Stu when he greets her. In the kitchen, she starts sobbing, possibly feeling guilty about what has just happened.
Stu and Mac are chatting along, when a little old lady, (Rose) flags them down and tells of how her hat (which was given by her late husband) blew off her head, landing into the lake as she was on her way to the hospital. Stu and Mac are unsure of what to do, needing to put their "thinking caps" on.
Toadie is working through some books when Libby stalks into the kitchen, muttering about how Toadie was her last option as Steph wasn't home. Karl rang her about his engagement and she is not too happy. Toadie looks stunned.
With Susan watching on in amusement, Stu and Mac try inventive ways to get Rose's hat. He tries using a long stick to not success. Next, he holds onto Mac to allow her to stretch out a bit more. Finally when all seems lost, Mac evilly eyes Stu and motions for him to get into the lake...which he does after much hesitation.
Libby can't believe that this is happening and asks Toadie if there isn't anything legal they can do to stop the engagement. She accuses him of being giving Karl his blessing by him staying out of it. He thinks she is just obsessing over the whole thing (though not to take it the wrong way).
Stu gives Rose her hat back and she goes along on her merry way.
Pan to a shot of Darcy still lying unconscious upside down on the stairwell when Rose comes in. In shock, she calls out Dr Tyler and quickly runs off to get help.
Karl approaches Susan to break the news to her about his engagement. As Susan has already her from Izzy (inadvertently, she adds) he doesn't need to explain. He says he didn't plan for it happen, but plans change.. Their divorce is nearly through, and she says he doesn't owe her anything anyway. They start joking away a bit, before Susan's mobile rings. Darcy has gone missing from his shift at the hospital.
Libby snippily congratulates Izzy on her engagement, citing her fast work. Izzy mutters something about the kitchen and walks away. Toadie walks in and he and Libby continue their conversation from earlier on. He only meant that she was obsessing over the negative things....but are there any positives, Libby asks?
TOADIE: It's like when you've got B.O. only your best friend is gonna tell you.
Although they're not his parents, he's noticed great things that have happened to Susan. Growing as a person, learning new things...but Libby points out that she only had to.
TOADIE: So you'd rather your parents stay together, but be unhappy?
The paramedics carry Darcy away on the stretcher as Mac and Stu discuss the situation. She tells him about another job, a burglary in Eden Hills that they need to check out after this. Stu realises that it's Karl's place.
Libby believes that if Izzy hadn't come along, than Karl and Susan would still be together. Toadie then changes the topic and suggests that Libby is in need of a hobby. She retorts that she does plenty of things! Like her writing (though it's usually about Izzy anyway), and...her fortnightly mother's group!
TOADIE: You know, you should go back to teaching. You were good at that.
LIBBY: Yeah my student feedback was great.
Connor busts in with a box full of electronic parts and announces Seamus' robot challenge. "We hoped this day would never come, but it has." Libby is utterly bewildered at this concept.
Connor excitedly explains to Libby that a robot annihilation challenge involves the building of a super duper robot and then the two bots going head to head. It's a growing world wide phenomenal in fact. Toadie can't believe that Connor is participating in something so nerdy and lame. Libby agrees, saying it's almost "as lame as those people who get together and dress up in medieval clothes!" Libby and Connor start howling with laughter, while Toadie weakly agrees.
Stu debriefs Susan and Karl about Darcy's condition, he has apparently been unconscious for about 2 or 3 hours. He hands Karl a plastic bag full of Izzy's jewellery, stating that Darcy has been up to other things. Karl, of course is outraged at this fact and immediately goes to call Izzy so she's not shocked when she sees the police their place.
Izzy serves customers their cappuccinos, but is very shaky when doing so. Someone is already using the phone, chatting animatedly.
Susan stresses that she thought Darcy had changed! They want to see him, but are informed he's still in emergency in a coma. Nurses then wheel Darcy by and they're just shocked at the sight. Karl comforts Susan.
Connor is sick of Toadie's whining and suggests he help build the robot. Cut to Toadie and Connor crouching down on the floor discussing the best way to attach the robot's weapons. Toadie doesn't want his robot to have some sort of wussy, nail-cutter weapons of a robot! They need a plan. Next shot of them is showing some hand drawn blueprints to Libby. She notes that they'll need to call NASA for spare parts. It's back to the drawing board for the boys.
Susan can't believe she believed Darcy and gave him another chance but Karl says that she is a good, caring person and Darcy took full advantage of it. She's doesn't want to see him when he wakes up, or if he wakes up Karl notes. She rests her head on his shoulder and the two share a nice moment until he realises he still needs to tell Izzy about the flat.
Connor and Toadie are in deep analysis about the best way to build the robot (lots of "scientific talk") when Libby checks in on them again. She's brought a whole arsenal of electronic beauty products much to the boys amusement. She shuts them up by demonstrating what they're able to achieve when used in a different context.
Curling iron = able to become a melting rod and destroy the plastic exterior
Hairspray = able to short-circuit any challenger within a 1 metre radius
The boys are happy with her evil ways of thinking and she's proud too!
Karl and Izzy's Flat
Karl informs Stu and Mac that nothing like electrical equipment is missing, only the jewellery. Mac thinks that's what he would have done, as it's harder to sell large items without receipts. Karl comments that Darcy could have put this all behind him.
Susan sits by Darcy's beside asking why? Why did he do it when he could have had a second chance and turned his life around?
Karl and Izzy's Flat
Izzy explains quite hysterically that she left the jewellery on the table, meaning to get it cleaned today but forgot. Karl calms her down, saying it doesn't matter any more. Mac and Stu go to leave, though they haven't got any fingerprints (Darcy doing the same thing with Ruby), they probably have enough evidence in order to charge him. Izzy asks how they'll charge him while he's in a coma....and Karl says he spoke to the doctor and the likelihood of Darcy awaking is very slim. Izzy has an expression which seems hard to read...guilt? Relief? Once they're gone, Karl comforts Izzy as she was scared about what could have happened if she'd been there.
Susan gets up and after some hesitation, kisses Darcy on the forehead.
