Fringe

A lot happened in this episode. A lot.

We begin with frozen heads. Of course we do. This is Fringe. My man Curtis from 24 shows up and hijacks a cryogenics company's truck full of heads. His buddy is shot to death and bleeds mercury.

Evil!Curtis is another other-universe shapeshifting soldier, working with Evil!Charlie, and they're hunting for someone's head. Evil!Charlie isn't feeling so good because I guess the bodies have a bit of an expiration date if they don't get enough mercury. His face basically starts to melt. He cracks open a ton of thermometers, drinks the mercury, and it holds him together for a little while.

Walter feeds Olivia some kind of worm smoothie that he says will help her get her other-universe memories back. She gets flashes of William Bell and the Twin Towers as the episode goes on, finally passing out and recalling an entire conversation they had about other-universe machine/human hybrid shapeshifters, known as the First Wave. Bell says the soldiers are looking for someone who can permanently open the door between the universes, and shows her a symbol that will be on their leader.

Walter figures out that the woman they had thought was the shapeshifter wasn't, and therefore the shapeshifter is still out there. You think they'd recall that Charlie was the last person to fight with it. Walter tracks down a chick he experimented on back in the day, a chick who could identify the other-universe shapeshifters. Time to do the brown acid!!!!

Meanwhile, Massive Dynamic is working on the shapeshifter's device - and they can extract the image of the last person it copied. Guess who it looks like? Olivia's with Charlie when she sees that it's him, and Charlie beats the living hell out of her. She fights back though, and eventually shoots him repeatedly. R.I.P. Evil!Charlie. Damn. Poor Olivia, having to kill her BFF.

In the end, Evil!Curtis finds the head he was looking for - their leader. It starts to reattach itself to a body with its mercury/blood stuff. Ladies and gentlemen, we have another other-universe shapeshifting soldier. The big poppa.

This Week's Code: MEMORY. All alone in the moonlight....
