I had posted this question over at IMDB and got this very logical response that I believe is correct due to their reasoning. It is Snow!

I believe it’s young Snow because it would make more sense for Henry to be trying to find answers about EQ hatred toward Snow while MM is in jail than for him to be interested in Alice in Wonderland when he hadn’t even met Jefferson.
