This is interesting, logical, and frightening.
If Session (as a Senator) was privy to this whole scheme, is this why he recused himself, step away from it, and swoop back in for the kill? Or, am I looking at this wrong?
You mean if Sessions was privy to this before the election? If he had heard about it (of course he was not a “friendly” so he probably did not know at that time), but if he did, he certainly would have informed Trump. If he knew about it, I doubt that would cause him to recuse himself; AFAIK his recusal is solely due to having helped Trump in his campaign.
