See, my first thought was a Greek Mythology AU featuring lots of drunken flute-playing (Lance), mischievous scampering (Lance) and nude discus throwing (everyone else).

But no! Now I'm thinking the right way to go would be a non-AU in which Lance just snaps one day, starts wearing the wig and diaper and eyeliner everywhere he goes and calmly refuses to discuss it with anyone no matter how much they pry. It could be a gritty psychological drama(!)...um, of sorts.
