So where almost everything is happening, then?

And yeah, it isn't something I'd think would be a problem in this particular canon off the top of my head (although I'm kind of surprised that nobody's looking for nightmarish intentionally-terrifying Erik/Shaw... I have been in fando way too long, I'm going to go bleach my brain now.) That said, I'm kind of against banning potential story ideas in any form - I'm a big believer in 'anything can be good if you treat it really carefully.'
