Oh yeah. In fact, all the council members are at the Council of 7 waiting on me while I finish up a few quests so I've already taken care of the Dwarven council member as well.
When I talk to him, he says, "once you get the breastplate and the heartgem, I'll give you the helm" but there is no response in my list of choices that says, "DUDE! I have them both right here! Hand it over!"
lol!
