Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

I have no doubt whatsoever that the man that Oswald was talking to in the hall and asking him what he had against something was James Bookhout. So, we can compare him to the mystery photo.

And it compares very well with no disconnects, although I'll admit that there isn't a whole lot of visual data in the top photo. A big factor is going to be whether someone can come up with a provable other identity for him. We'll see.
