Fringe

Olivia returns to the lab.  "Please tell me you have something better than what you are wearing on your head!"  Walter steps forward wearing a tinfoil hat.  "This has nothing to do with the case.  I don't like it here; I think they're reading my thoughts.  Astrid also has one on and she wears it with style.  Walter has put together an EMF device that will give Peter a window to fight off Tyler's control.

Peter and Tyler arrive at Renee's house in Maryland.  "Mom!"  Peter gets them all inside.  Tyler is thrilled to have found his mom.  He understands why she left (because of his dad) but now they have money and they can run off to Costa Rica to be a family.  Renee starts to explain what is going on... and then her husband comes in.  Tyler thinks that he is the reason she is hesitating.  He orders Peter to get the gun.

Just before Peter can shoot Renee's husband, Olivia and Broyles arrive on scene.  Broyles tasers Tyler to no effect.  Tyler makes Peter shoot Broyles and they take off.  Olivia, seeing Broyles was only hit in the arm, rushes out to follow them.  She gets picked up by Walter and Astrid, who have spotted Peter and the missing car.  They get close enough for Walter to use his EMF device.  Tyler loses his concentration and Peter steers them into a light pole.

Walter hovers over Peter until he regains consciousness.  He tells Peter that Tyler was knocked unconscious and they have given him a sedative to keep him that way.  Back at home, Walter still hovers.  "You were abducted, of course you need crepes."  Peter is somewhat disgusted by the fact that although Tyler killed a bunch of people, he is going to end up free after a little therapy. 

That's what he thinks.

Nina sends an email to William Bell, updating him on the status of the Carson-Penrose experiment - one of the subjects did develop mind control.  Unfortunately, Tyler 5 also accessed his records and found out about his surrogate mother.  Still, the experiment was a success.

And we see Dr. Carson wheeling a gurney holding a sedated Tyler down into a holding area where several other Tylers are resting.
