Okay, this falls into the weird stuff file, but I had completed a task for Farkas, and moseyed up to Jorrvaskr. He wasn't inside, so I ambled out the door to to the patio. Didn't see him there... but wait! Aela snaps out her favored toy, the Sanguine Rose. A very, very, oh so very short battle and that drunk Torvar is dead! But why? I dunno, but I approve.
Oh, and that jerk Athis is dead, too. Bonus!
