I can give peter a pass on trusting adam so much, miya is a diffretn story. peter was imprisoned witht the guy and he pretty much got him out for one, plus peter has this chick lost in the future so all thats on his mind really is destroying the virus, also his mind reading seemed weak since it took him awhile and when u hear it it kinda sounded broken up,

miya on the other hand pretty much left her brother for some guy she doesn't know, believed sylars story on why he killed hios mother without even questioning it at all, but not listening to her brother when he said he didnt hate her lol.
