Ever wonder how Patrick Jane came to work with the gang at CBI? Creator Bruno Heller satisfies that curiosity with tonight’s flashback episode, which also is the series’ milestone 100th installment. It takes place eight years earlier and viewers see Jane emerge from his mentally fragile state in the wake of his family’s murder by Red John. It’s a fun opportunity for the actors to throw off the relationships they’ve already established and get a glimpse at the pre-Jane dynamic. (All of the regulars are in the house except Van Pelt, who had yet to be hired.) It also gives Simon Baker (pictured) a chance to show off a vulnerable undercurrent to the normally cocky Jane.
