*mildly irritated when Q describes what he thought Sirius might be like, but doesn't really take it personally, and both his expression and tone are amused when he speaks* *picks up the book and flips it open at random* So I can't be trusted to give you tea in a proper cup, but I can be trusted to help you with complicated magic?
*doesn't recognise the authors that Q mentions, but smiles, and leaves unspoken that meeting the same people in different dimensions is nothing compared to meeting yourself in another dimension#* There was someone who shared your name where I come from, but I didn't know him well. *also leaves unspoken that he knows of that Quirinus Quirrel through what Remus had told him, even if he didn't know that Quirrel personally* Since you brought it up, may I ask what the grudge was about?
#Sirius is in Margate via the Veil and... Well, he's travelled through a LOT of different realities :)
