Summary

 * "Do You Take Dexter Morgan?"

While going through mail at Rita's house, Dexter notices a card from his future mother-in-law, Gail Brandon. Rita tells him that her mother won't be attending their wedding because she returned to teaching and can't take time off.

Dexter then reads Gail's card, wherein she hopes that the "third one is the charm." Puzzled, Dexter asks Rita what she means. Rita unconvincingly says it refers to her third child, but Dexter feels she is lying to him.

Later at the station, Dexter runs a background check on Rita. He's surprised to learn that Rita had a six-month marriage she hadn't told him about. She was sixteen at the time, while her husband, John, was twenty-one. Dexter debates confronting Rita about her secret, but eventually decides not to mention it, since he keeps so many secrets from her.
