By the very virtue of making the referencing you are immediately assuming something. Dont rate this comment at all.The interest in this bloke has died out a bit since the press conference video rolled out, and I can't help but notice that the BF podcast touched on a perceived issue with Harrison.
I recommend everybody go back and watch the press conference again: watch his pacing of his speech patterns, and his concentration and eye contact. He has a lisp and a rough looking head, but I don't think it's fair to suggest anything else, at all.
