Nick is played by Windell Middlebrooks.
Mac is annoyed that Carmen married Nick after she had her penis removed as she was supposed to call him after the operation. Mac attempts to condemn them with the bible verse Romans 1:27, to which Nick responded with Exodus 21:20 as a comparison to the book's logic. It is discovered later that Nick cannot have children and that Dee offered to be a surrogate mother for the couple's son. Carmen had her sperm frozen sometime before her operation and they used an anonymous egg donor and then used Dee as the surrogate. Both parents are thrilled.
