Heroes 4-10 “Thanksgiving”

Lydia demands that Hiro take her back eight weeks, to Joseph’s murder. Hiro says no, but then does it anyway. They notice Suresh, and then see Samuel confront Joseph. Lydia follows them, but Hiro says it’s dangerous to be in the past, lest they step on a butterfly. For a guy who’s been so cavalier about changing the past this season, that’s an odd stance to suddenly take.
