I'm betting it is someone we have yet to be introduced to. I also got the strong impression it was one of the "Heroes" of his generation, by what he said and how he said it. The comment was more than recognition, but of familiarity. He knew the assassin.
Besides all of that, did we ever find out what his power was (Takei, not the assassin)?
