I think they will keep Bennet powerless in the super heros sense of the word. It works so much better if the guy pulling the strings and having all the cards is a normal chump. It puts things more in perspective when you look at how it shakes down and underscores the fact that you don't have to be able to fly, or melt steel with your mind, or have a healing factor to be powerful.
As for Bennet being Linderman, I can certainly see it, after all, he has ties to nearly all of the "heroes". However, I think Linderman may end up being a seperate intety altogether. I was thinking about the season finale that will eventually get here and thinking it will NOT be a cliff-hanger, since a comic book story arc tends to end in the Climactic Battle and it occured to me that there may be an epilogue leading into the next season's story arc. If that's the case, then I think we will se Linderman in that episode, or maybe just hear a voice-over from him or something.
