silar question - spoilers
i'm getting a bit confused with silars powers here, can someone enlighten.
i've seen the first season already and am watching again, last night was homecomming, just after 7mins to midnight
it seems quite clear in these eps that silar has to physically take the powers from others - removing the brain etc..., unlike peter who can absorb when simply in the same area. we also see silar's first encounter with eden - where she uses the voice on him.
however, in later episodes, silar is able to use compulsion on eden, and after encountering hiro, is like peter able to withstand his frozen time field.
so, does he have to take power physically (as we see him in 'six months ago'), or can he simply assimilate like peter?
