(S02E05) "It's always the popular ones who think they can get away with murder." - Loker

Easily the best episode of Lie to Me to date, I have to wonder -- I can't be the only out there who's just dying to know more about Cal's past, right? Lennie James guest-starred as Terry Marsh, one of Cal's old crime pals and his arrival created so many questions that have just pushed aside anything else going on at The Lightman Group. Unless Gillian or Loker turn out to be serial killers from past lives, nothing else really matters right now besides Cal's history.
