Fringe returns tonight with the episode ‘Back to Where You’ve Never Been,’ and we’re all excited to see Peter venture into the “new” (we think, it’s confusing) alternate reality! Check out a few spoilers about the episode from Josh Jackson.

Joshua teases the meeting between Peter and Walternate in a TV Line interview, saying:

It’s not that easy. It’s, ‘Hi, I’m Peter Bishop and you’re my alternate, alternate real father who doesn’t know that I survived, but I did, in a universe you’ve never been in.’ […] To a certain degree he’s the same Walternate we used to know — he’s got his fingers in all the pies — so I don’t think he’s ever surprised by anything. But as you will see, his motivations in this timeline are completely different than they were as we used to know him. It looks like a duck, walks like a duck and quacks like a duck, but it’s not a duck in this case.

Fringe airs tonight at 9/8c on FOX!
