So its pretty obvious to me that the man who is half responsible for Henry's existenceis probably using an alias when he meets Emma. He's the only character, that I'm aware of who's name is pretty much identical to an actual real person. Now, Once Neal and Real Neal do share some similar personality traits, namely being a petty thief and fencing stolen goods in their youths.
What do you all think? Is it an alias thats intentionally meant to be recognized as one, or is it really his name and all just one big coincidence?
