User blog comment:You Know I am Awesome/Identity of The Man in the Mask/@comment-20053828-20160517013318

I really think it is Hunter's father. It is common theory and I'll tell you why. Hunter said he doesn't want to be alone again to Caitlin and he has a great deal of reminders, prisoners, who he kept including the man in the iron mask. It seems like this man is his earliest prisoner. I think that Hunter, even though he didn't like his father wanted to keep him to satisfy his lonelyness that he had for so long and also partly for revenge for giving that lonliness to him. He basically has the mask on his head to shut him up from insulting him. It makes a great deal of sense and I doubt that the writers are going to give anything really complex.
