He's always been a prick, as far as I can tell. Claims to be a lawyer, but watch any discussion he has about legality. [ No further comment necessary. Severus has only a limited awareness of muggle legal systems, but even he can tell there's something wrong with how he talks about it.

But-- on to something a bit more grave. ]

Something happened to him on the colony - that he didn't deserve. A dark wizard from some other world went after people. No one deserved it, even him. But Black new, and as far as I can tell, didn't help.

Instead whatever he said to him resulted in him cornering and attacking me. He's a telekinetic.
