The final episode of series one when the boys all jump together on the trampolines.
The episode Girlfriend has Simon warning Will that Charlotte will break his heart. Will disagrees and the two argue bitterly and go their seperate ways. After Will messes things up with Charlotte, he sees her looking for a new man at a charity dating game, the final twist of the knife. Later, when he's at home with his mum, Simon and Jay come over to invite him to come and watch Neil on his own embarrassing date. The fact that these two (particularly Jay) would go out of their way to cheer Will up is really quite nice, especially considering how cynical the show usually is.
The group hug from the film.
"Do you want a lager, Si?"
Neil's offer to buy Jay chips after being dumped.
The entire sixth form standing up for Will and telling Donovan to leave him alone in "Xmas Party".
