It's been awhile sisnce I've posted/veiwd the boards here so maby someone else has brought this up.
After last nights episode I got to thinking about his power. I remember a while ago people were discussing wether his ability only blocked mental abilities or physical abilities or both. Now we know it at least partialy blocks mental abilities (parker was able to hear a little of what Noa's conversation with the Hasian, though he had to over exert his power to do so). We know he was not able to block Nathas Flying. He was able to block Hiro and the fast girls (cant remember her name) powers. And he was able to block Arthurs powers. So from this the only power he was unble to block at all was Nathan, who got his power from this formula.
Bleh... I had to go afk to take care of some stuff and lost my train of thought.
Any way I think what I was getting at is what roll could his power play against or with (if arthur decides to kill him/take his power) Arthur later in the season.
