From what he tells me, he tried to transmute Edward, and you found them both. You saved him from bleeding out on the floor and you took care of.. what was left of Edward.
I guess you were pretty protective towards him after that, but he says I was the one who transferred him out of the dorms and into your house, so I suppose it wasn't his choice, but mine. And from what he's told me, I made the right choice.
