This series just keeps getting better. Evil Olivia has come across the barrier between universes and has infiltrated the Fringe Division. Good Olivia is on the other side where they've drugged her to think she is Evil Olivia and is working for them.

Walter drops acid in the morning to expand his awareness and his partner died and left "Massive
Dynamic" and all it's resource to him. He is infatuated with chocolate pudding.

Peter is still pissed at Walter for stealing him from his parents in the alternate world but he’s getting over it. Peter is also enjoying Evil Olivia’s advances.

There was one scene in this week’s episode that startled the hell out of me. The stole it from a recent TV commercial.

Well I don’t know how easy it would be to pick the series up at this point but it would be worth a try.
