Dexter: 'Do You Take Dexter Morgan?' Preview

And the time has come for the season finale.

On December 14th’s “Do You Take Dexter Morgan?,” the twelfth and last episode of Dexter’s third season, Dexter moves on from his troubles with Miguel to his potential problems with the lawyer’s brother, Ramon. All seems to go to plan, until something unexpected interferes with Dexter and Rita’s impending nuptials.

Meanwhile, Debra hits a snag, too, in her quest to become a detective. As soon as she gets news that a shiny shield might be in her very immediate future, an unforeseen development threatens to make such a promotion an impossibility.

The two sneak peeks for the season finale are Dexter’s Apartment, which shows things getting a bit tense for Dexter when the police search — or rather, totally tear apart — his home, and Secrets, which features Laguerta questioning Dexter about Miguel. Find ‘em both after the jump.

Dexter airs Sundays on Showtime at 9pm EST.
