Kim is a tow-truck driver.
A weak and tired Castiel nearly crashes his car into Kim's truck, instead he drives into a tree. Kim offers to repair his car and lets him and Hannah stay inside her house for the night. She even offers them her leftover of three-bean surprise, much to Hannah's confusion.
By morning, the car is fixed and Castiel, having fallen asleep, wakes up to find Kim's daughter Frankie sitting next to him. They have a conversation about dreams while Kim and Hannah look on. Kim assumes the two are in a relationship, and is dismayed somewhat when Hannah denies this.
