Terminator: The Sarah Connor Chronicles
Busy appears as the Connors' extremely pregnant landlord and neighbor Kacy Cotton. She and Sarah have so far bonded fairly well because of the pregnancy, and Sarah has developed a protective attitude concerning her. In "Allison from Palmdale", Kacy has some complications with bleeding and cramps, and Sarah drops what she's doing to take her to the ER. Sarah stays at her side the whole visit, assuring Kacy that everything will be alright. The Ultra-sound technician discovers that nothing seems to be wrong with the baby.
When the baby's father shows up, Kacy hints at Sarah that she wants her to stay. Sarah does stay, showing concern about Kacy's reaction to his appearance at the hospital. Later, Sarah attempts to "check him out" to make sure he's not a danger. He appears to be an honest, caring man so Sarah backs off.
