This is an unsettling episode - the rounding up of 'different' people by someone who should know better. I felt discomfited, partly by the time change again - months after the previous events - and partly by what was happening on screen.
I think for the first time I actually cheered for Sylar, a character they started to allow to develop, but then decided (very abruptly) against it.
I will watch the next episode tentatively, fearing any subsequent plot developments, but something in me hopes they bring this series to a positive end. If they can really only imagine the world heading towards the dark place it was at the start of the third series (Peter being shot by Claire etc) then I don't think it's one I'll invite into my house on a regular basis. Most people are more positive by nature. I know I am.
