It annoys me that my primary fandoms of the moment are Peep Show and Glee, two shows that are essentially impossible to cross over. I tried to conceive of something involving Mark and Jeremy at school, but... no. Mark Corrigan cannot be a teenager. It simply doesn't work. He was born thirty.

Peep Show is generally quite a difficult programme to cross over with anything, possibly because its main characters are so incapable of normal human interaction. Try to have Mark converse with anyone but Jeremy and he immediately dissolves into panic, desperately trying to maintain his 'I'm a normal person, really, please believe this for long enough for me to get out of this conversation without humiliating myself' mask. I can't imagine he'd approve of Pokémon. Try to send him to Silent Hill and all he'll find is a piece of graffiti saying We considered sending monsters after you, but we decided you'd suffered enough.

The exception is Mark Corrigan/Luna Lovegood, which would be adorable. Mark would worry in her company at first, but eventually he would come to realise that she is a) equally bad at social interaction and b) not self-aware enough to recognise it and therefore probably not aware of how socially incompetent he is. He doesn't feel that he's at risk of fucking up their relationship every time he speaks to her! It's a miracle! Is this how other people feel in interaction with their significant others all the time?

BUT SHE KEEPS TALKING ABOUT THINGS THAT OBVIOUSLY DON'T EXIST AND IT MAKES HIM SO ANGRY.

Eventually, when she's staying over, she steps out onto the balcony to look up at the stars, leaving her wand on the bedside table, and Mark, in a fit of madness, locks her out. It's entirely reasonable; if he hears another word about Nargles, after all, he's fairly certain that he's going to snap and use an Unforgivable Curse on her, so morally this is almost certainly the right decision.

When she tries to get back in, fails and asks him to open the door, Mark is already regretting his rash action, but he's gone too far already; he can't back out now. He pretends that the lock has somehow become stuck.

"Just use an Unlocking Charm," she suggests.

Mark panics and snaps his wand in half. Why did he do that? That was utterly idiotic. And then, of course, he can't find an excuse for not using her wand to unlock the door, so in the end it didn't achieve anything. He lets her in, and she doesn't seem to suspect that any of it was intentional, but he resents her so much for causing him to break his wand that the relationship cannot continue.

...did I say it would be adorable? It would be adorable for a while, at least.
