I think, personally, you hit the ground running. Chuck, like Hiro, can seem to be very one-note, but he's a lot more subtle than Hiro is. I think you caught on to that very quickly.

As to losing his voice, I don't think you have at all, but I can understand your frustration in having no canon for several months. I don't know if you look for spoilers or anything, but, quite frankly, except for the commercials I haven't seen "boo!" about Chuck at all.

Also, you're playing in a bit a vacuum, which doesn't help. I mean, I have all kinds of "Heroes" people to play with so I get to explore all kinds of parts of the universe (plus having a larger cast to begin with).

I think you do an excellent job playing Chuck. You have his voice down pat and you understand his very gentle nature. I always enjoy playing with Chuck.
