what's the most unhinged sirius/remus combo of all your different siriuses sirii and remuses remi and what would they get up to?
ooooooh this is an amazing question, thank you!
the answer, of course, is the two feral smartasses: s&s&y sirius and pdsm remus. because oh my god they would obsessively hate each other.
they're both quick to judge and slow to trust, so I think they take one look at each other and go, "wtf is wrong with this version of you??"
a duel ensues. sirius is mystified by hedge magic and demands to know how it works. the next thing they know they're starting a revolution in whichever world they're in, but ONLY as begrudging allies who very much hate each other.
except apparently wanting to murder someone counts as an emotional connection, so the little demi switch in sirius's brain flips, and it flips hard, and wow okay their clothes are already off! but they still hate each other!! (no they don't)
... in conclusion, they absolutely do fuck. and also stir up a lot of trouble. and most likely get themselves killed the moment they realise they're in love :/
