Good point there, and too all the people who are saying that the room is blocking powers, any evidence or any ideas how it would be done?
If you tell me how exactly the powers work, I'll suggest a few ways how they might be suppressed.
Without over-analyzing anything, it's obvious they had some reason to believe that he wouldn't be able to escape even if they weren't watching him.
Reviewing the previous episode, when Glasses-man is 'interviewing' the Voice, it sounds as though her power was not suppressed, as her voice carried the same tones as other instances of her use of ability. I think that the ineffectiveness of her ability at that time came from the Haitian, who likely was preventing alterations to Glasses-man's mind, or possibly re-writing her imperatives before they could be acted upon.
However, Glasses tells Sylar that his abilities "won't work here" so that leaves us scratching our heads. It is also evident that the Haitian was nowhere nearby, as Glasses meets him in the front lobby of the building, while Sylar is locked up in the (presumably large) basement.
Personally, I would suspect some kind of manipulation, rather than something linked to the room itself. But, we won't know until the producers decide to stop teasing us and just tell us how it works. Probably after we fans have thrown it back and forth long enough to get a few good ideas out, and they can just pick the solution they like the best. After all, why pay a writer to think of an answer to something when fans will do it better, and for free?
