Grandma Miller (Marla Gibbs), starred in 227 (1985), which also stars detective Lydia Adams (Regina King). When Ms. Miller first sees Detective Adams at her door, Miller calls her "Brenda," which was the name of King's character on "227."
Just after detective Adams gets out of the pool, the scene switches to Cooper and Tang in the patrol car. Officer Tang says that the other officers now call them "the walking dead". Michael Cudlitz later goes on to play Abraham in the zombie series The Walking Dead (2010).
