After having just completed getting the Boomers to side with me, a new Quest has popped up titled "Don't tread on the bear" and says if I continue to work with Mr. House, the NCR will no longer accept my help.
My question is, is there anyway to switch sides to the NCR, or overthrow Mr. House and use his power to help the NCR. I mean, I know I can side with Caesar but as far as I know, I haven't previously had an option to singularly work for the NCR. And for all his talk of change, he's just a robot and I don't want to go to war with the NCR.
Any help is appreciated
