In this third episode, Olivia eats the brains of a hit and run victim, and she discovers that the dead was actually a contract killer, involved in one of Peyton's cases.
The episode is fun, not complicated and keeps things going, with a new case, relationships evolving (specially Peyton and Olivia's) and a new personality for Olivia. Rose McIver does a good enough job, but the voice-over constantly remembering us that she has no feelings and is cold-blooded (more than normally, of course) because she ate the brains of a psychopath, makes the characterization very weak. If we have to be remembered all the time that she is very cooooooooold and detached and will see someone she knows be killed without caring, there's a problem. So this episode new "power" is kind of watered down. The case is good enough, on the other hand, so it will keep us interested. And we also have the interesting discovery of another zombie...
On a last note, Blaine's plans seem clearer now, and it is starting to look as if he has a very very bad idea in mind...
