I was thinking Arthur's power could also work as a "cure" for the other gifted people who don't want their powers, like Maja or Tracy.

And what do you think about Arthur touching Mohinder? Would he be able to stop and reverse his mutation?
Would he become a 'monster' aswell?

I'm really wondering about Mohinder, if so, Mohinder better get there fast and attack Arthur. I want the old Mohinder back.

It looks like he will be taking maya's power from the sneak previews of next episode
