How I can tell I have played the game too long: I tried to click on the dog to see if he was aggro.
Couldn’t figure out why the mouse wouldn’t go over to him.
(I’m pretty sure this particular dog is Hostile To All Factions. The St. Bernard is Friendly To All Factions, including Dognappers In Trucks, as has been demonstrated twice.)
I have no really specific reason for wanting to kill Regthar Deathgate. It just seems like he might find it a welcome change of pace.
