Quote from Carla in Rat Girl
Lilith: No, you don't understand. Usually we don't get attached to the rats, but this one was so special. We even named him. Everyone in the lab called him Whitey. Carla: Are you sure they weren't talking to you? Lilith: No, Carla. They were talking about Whitey the rat. Carla: Okay, I'll ask again. Are you sure they weren't talking to you?
