the end of the ‘sirius black learns about muggle appliances’ is sirius black, being on a plane for the first time with remus

and they board and sirius is like ‘remus. this is like being toothpaste. this feels like a toothpaste tube. we’re minty. we’re going to die.’ remus is like we have not even taken off yet calm down

the engines turn on and sirius just SHRIEKS and grabs remus’ hand so hard it nearly breaks remus’ fingers

halfway through the flight sirius is like ‘I need a cigarette this is terrible’

the flight attendant races over like ‘SIR there’s NO smoking on this flight’ and sirius just whips around like ‘you’re damn RIGHT THERE IS YES THERE IS M8’ and remus is like please excuse him i am so sorry

remus brings calms forté for when sirius gets really nervous (which is, for people who dont know, essentially pills to knock you the FUCK out during transatlantic flights) and sirius just gets HIGH AS BALLS and turns into padfoot and remus is like THIS WAS A TERRIBLE IDEA AND CANNOT GET WORSE because sirius is just whimpering the entire flight as a dog and the flight attendant comes back over completely baffled for like 8 different reasons but the rest of remus’ interaction with her is basically like

“sir is that dog trying to smoke a cigarette”

“HE MosT CERTAinLY IS NoT”
