So the only family that Collins has is his father and mother, neither of which we know much about canonically other than that his father was shitty by Deinns's point of view. Which is probably true as it's heavily implied he was physically abused.
I suspect Hannibal would take to Collins like he would to one of his more 'interesting' patients. >_> I am going to try to figure out an angle for Hannibal to at least approach the Barge politely initially. Should be fun to see how things play out.
