The young woman staggers as they land in what is presumably her home, presumably from having to unexpectedly apparate three people. It's probably a minor miracle that no one was splinched.
Automatically Remus reaches out to steady her, only to have his hands slapped away, and a bloody terrifying glare levelled at him, which, yeah fair enough.
"Stay back!" She – actually he? maybe – raises his wand mere centimetres away from Remus' nose. "What do you want with me?"
"I don't." Remus sighs. "I just want that dog."
His expression manages to sour even further. Typical bloody Sirius, charming everyone.
"Listen, can we start again?" He says placatingly.
"NO! WE CAN'T 'START AGAIN'! YOU HITCHED A LIFT INTO MY HOME!"
Right. Yeah. He had done that.
"You're in danger." He can't help but dart a look down at Black but discovers to his horror that the dog has skulked off.
"Oh yeah." The young man scoffs. "Sure. Just because he was violent around you does not mean that Snuffles is a bad dog. You never gave him any other choice."
That's…what the bloody hell is he talking about?
