Wow, I can't remember the last time Lie to Me left me glued to the television. Deviating from previous episodes where Cal messes with random people, "Dirty Loyal" puts everything on the line, testing how far everyone would go to protect their partners. It's also the best plotted episode in a long while, without those pesky "twists" which end nowhere.
With Wallowski under IA investigation for helping a gang member along with her partner, Cal does his best to protect her, all while the police are leaning on Gillian to find the truth. Of course Gillian knows the truth--Wallowski was covering up for her partner, knowing the gang member was his son. And she does come perilously close to incriminating Wallowski. However, Cal manages to dissuade her at the last moment.
The best part is that the current problems between Cal and Gillian have only gotten started, and "Dirty Loyal" kicks it up one notch. I can't wait to see when the inevitable blowup occurs.
Score: 9.2/10
