The case of the week seems like a poor excuse to get to know the characters more on a personal level. The case is a about amiddle aged man who seeks revenge on people by melting their loved ones brains through a computer virus. Pretty silly and a very weak fringe case, the cast doesn't seem that bothered either.
This week was more about the characters and their family's. Olivia's sister and her nice is still staying at her house and that poor little girl almost got her brain melted, good thing she has a super aunt! It's nice to see this different side of Olivia, loving sister and aunt.
Peter tries to protect Walter from the mother of his old assistant who died in a accident years ago in his lab. When Olivia finds out what Peter is doing they have a little argument, Olivia believes that Walter can handle a meeting and that it only will do him good to face the past. When they solve the case which had someconvenient father/son issues Peter agrees with Olivia and set up a meeting with the mother and Walter. Turns out, the mother wasn't angry, she only wanted to ask Walter about her daughter, how she was before she died and so on. Walter talks about his former assistant in a nice, loving way, connecting with the mother. Best scene in the episode.
I'm a bit miffed with Peter and Olivia's sister, flirting!?!?
