probably nothing, other than not trusting you with van, which he already doesn't. Unless Acedia got upset by Luke getting upset at you killing his master.

Luke is FULLY AWARE Van is an awful person who deserves awful things and fully aware Acedia is crazy. He'd yell at Acedia and make it clear that Acedia wasn't doing this for _Dawn_ but for _himself_ but he wouldn't dump him or anything.

is there any chance at all of acedia deciding to stay at aather instead of going back to canon?
