Freak of the Week: Man is attacked by an invisible force that turns him into an albino. A dead albino. This invisible man uses his victims' pigment to become visible, then fades to invisible again. I'm thinking that if he wants to make it more permanent, he should be killing a few black people. Even just Broyles might do it. Just sayin'.
Olivia's getting migraines and is on some kind of medication. She and Lincoln engage in some late-night-diner bonding. Meanwhile, Broyles has assigned a bodyguard/nanny to Peter - and Peter gets to live in his old house and gets a $200/week allowance! Peter's working on his machine so he can get his sweet ass back to where it belongs. He wants his Olivia back.
As a child, the invisible guy was a subject of genetic testing (done by a subsidiary of Massive Dynamic) that essentially turned him into a giant chameleon. Walter does some experiments and makes himself an invisible mouse, determining that it's visible under ultraviolet light. They hunt the dude down and he dies - that's pretty much the long and short of his story. It was about an invisible guy who just wanted to be seen.
In related news, Olivia thinks her childhood drug trials led to her having stunted emotions. She thinks it's weird that Fringe-y things don't bother her like they probably should.
Olivia is prepping for a 3 AM date with Lincoln when a gas fills her apartment, knocking her out. Men enter and do some kind of procedure (taking something, injecting her with something, I'm not sure)... and Nina is with them. Nina's bad!
Walter's Food Thing of the Week: He eats onion rings during a remote autopsy. Double dipped in beer batter, I think he said. Mmmm.
This Week's Code: DAVID. Who the eff is David!?
The show doesn't come back until mid-January some time, but when it does, it's time for Peter to cross over to the Other Universe to look for some answers. The return of Alternate Lincoln Lee!! YES!
