Fringe Question...

I thought tonight's Fringe was supposed to be a new episode, and it is one that I haven't seen before. However, I could have missed one, so it might just be me.

But...there's a problem with that.

Okay, there's that one BIG THING with this episode that makes it impossible to be new or at least new and the next installment in the series timeline if we are moving chronologically.
