Thanks to "Delinquent," Lie to Me viewers witnessed family drama on multiple tiers last night. It was mixed with some very touching moments, as we got to see more Gillian’s maternal nature with a nice mix of vulnerability.

Okay, raise your hand if you knew Ria Torres has a sister. Much like Eli, I was surprised. Granted, it was a good surprise because it also gave us more info on Ria than I think we have really gotten in two seasons. I also thought seeing the guilt, love, and pain that comes with being siblings in a dysfunctional family was well portrayed by Monica Raymund as Ria.

Her guilt at the end of the episode was near tangible when she was explaining to Lightman about how she had let her sister down and had broken her promise.  I hope we get to see more of Ava in the future and that we get to see the two of them grow closer together.

I very much enjoyed seeing Gillian’s vulnerable side, along with her motherly instincts.

Seeing her step up to try and protect Ava - between cracking the intruder with a pan, not calling the cops so they would not take her back, and coming to her defense with Ria - you could see strong glimpses of how Gillian would be as a parent. I especially loved the tender moment with her and Lightman after the attack. It showed us how much Lightman really does love her and care for her.

I was super thrilled when the psychologist from the correctional facility showed up with flowers at the end. She really needs someone to treat her special again. Given they are in the same field, I think they could do very well.

As for family drama of Ria dealing with her sister and Lightman dealing with Emily learning to drive, I think we ran the full scope of possible emotions. Tim Roth is so amazing as Cal Lightman and at the end when Emily passed her test I loved how proud he was of her. 

Is it just me or is Lightman a bit bipolar? Sometimes he seems as giddy as a school girl - such as when he was on the witness stand, or in this episode when he was breaking Ava out. Other times, he seems so somber and a bit of a jerk. Don’t get me wrong, I think it adds some very nice depth to the character. I am just trying to figure out if it is intentional or something Roth is accidentally doing in his portrayal.

What did you think of the episode? Did you like Gillian’s new suitor? Did Ria do the right thing by allowing her sister to go correctional school?
