I thought it may be resolved without any bloodshed but grenlet never should have brought layala and minny with them. now third castle will be destroyed for sure. no leader can stop it.
so, either grenlet will choose his next words *very* carefully, or Quinn will reveal the return of the punishers by first using shadow lock to secure his wife and child and then shadow eater on all the nobodies in the room.
He is screwed too bad if he didn't try and force Quinn's hand it would have been alright as he was going to punish those who went after his family. Hoping Quinn makes him a subordinate though.
