Showtime has provided us with two brand new clips from the upcoming Dexter episode, Lost Boys, which will air on Sunday, November 29 at 9 PM ET only on Showtime. Click below for these new clips, which feature Dexter and Rita taking their son in for booster shots, and another clip featuring Dexter keeping tabs on Trinity.

Dexter finally believes he understands the beast known as Trinity. But when a ten-year old boy goes missing, Dexter is forced to question everything he's learned up to this point. It's a race against the clock. And with each step forward, Dexter has to confront the real possibility that he may have more in common with Trinity than he'd like to admit. Secrets abound - from Cody, who is forced to defend one of Dexter's lies, Masuka, who can't bring himself to confess what he witnessed at Thanksgiving, and Debra, whose recent discoveries force one of Miami's finest into making an impossible decision.
