The Fringe cast spoke to Sky TV at Comic Con about the absence of Peter and what it’ll mean for the remaining characters, especially Walter.

In the video interview, Joshua Jackson explains what we’ll be exploring in the world without Peter – and among other things, he reveals that we’ll find a Walter “who never got fixed.” Anna Torv talks about how the characters will be building their relationships again in a whole new way, and whether the alternate versions will be able to work together. John Noble says that Walter will still work for Olivia, but won’t have “that lovely, softening element.” In general, it seems that Walter will be suffering from the absence of Peter, whom Blair Brown explains has a “healing” effect on him.

You can watch the video interview with Josh Jackson (Peter), Anna Torv (Olivia), John Noble (Walter), Lance Reddick (Broyles), Jasika Nicole (Astrid) and Blair Brown (Nina Sharp) here at Sky TV.
