Yes, but I was sort of thinking it would be Rita's mother. She didn't come to Rita and Dexter's wedding but sent a cryptic note saying maybe the third time's a charm. That's what tipped Dexter off to the fact that Rita had been married twice before. And there was no mention of a father. But now we have these two imperfectly seen grandparents who stay in the backgrounds of the scenes and don't speak, clearly brought in for the sole purpose of taking the two older kids off Dexter's hands.
But hey, Lorna, you got your two Survivor challenges tonight!
