If it wasn't for the first 10 minutes, this episode would be forgettable. The intro where Cal and Gillian were pretending to be a couple who want to make a porno is awesome, we get a kiss and Gillian's hand is awfully high on Cal's thigh. You can tell Gillian starts to struggle when talking about a threesome, but never fear, Cal jumps in for the save. Cal later teases her that most of what she said was part of the act except for the part about her wanting to be tied up.
The rest of the episode is okay, they are trying to find a missing 18 year old girl that has disappeared into the porno world. They find her relatively early and are trying to get her back with her Dad, who she thinks killed her mother. A lot of Emily in this episode, which was the other saving grace.
Side story; Cal pits Torres and Loker against each other for a promotion. They end up hooking up (all you see is a kiss but it's implied that they slept together). Poor Loker, who knew he was such a romantic, wants them both to turn the promotion down if offered so they can have a shot at a relationship. Torres says if he turns it down and it's offered to her, she's going to accept it. Thus ends the short relationship.
