'Fringe': Season four premiere in pictures

Where is Peter Bishop? Fringe returns to Fox tomorrow night, but it's a very different show to the one we left in May - Joshua Jackson's roguish lead is gone and both Olivia (Anna Torv) and Walter (John Noble) are feeling his absence, without ever actually knowing that he existed!

But there's also a few promotions in store. Astrid (Jasika Nicole) is a field agent in this strange new world, and remember the loveable 'geek' version of Lincoln (Seth Gabel) from the original universe? He's back and is now a full-time member of the Fringe team.
