Now, for my hypothesis:
Spoiler
I think Dr. Mitchell is Mr. House. I just came to this realization when I decided to visit the doctor. He slightly resembles him from the picture of him on the computer in the Lucky 38 in my opinion. And Dr. Mitchell said he had something taken from him, but you aren't told what it was, you're left to wonder what it was. If he was Mr. House, that thing that was stolen from him would be the Platinum Chip. I don't know, there just always seemed to be something peculiar to me about Dr. Mitchell, like he didn't seem like any wasteland doctor, he seemed to be a lot more to me. And Victor, who is of course a robot from Mr. House, happens to bring you to Dr. Mitchell, and Doctor Mitchell is somehow able to revive you after you've been shot in the head. That seems somewhat miraculous to me, miraculous just like Mr. House's method of staying alive hundreds of years after the war when he was from before the war.

I'm probably wrong, and I'm probably not thinking about a bunch of other factors that would make this conclusion impossible, and keep in mind that I just came to this conclusion in just a few seconds of thinking, but it just makes sense to me now that I think about it. Anyway, I may not read this topic after I've posted it, and may not come back here until I've finished the game at least once, but I just thought I'd post this hypothesis.
