- Les Yay: Derpy really likes GLaDOS's voice.
- Shipping: People on the chatroom say that the Doctor likes Derpy like a special somepony.
- The Woobie: Derpy sometimes gets like this; when she first gets shot at by the turrets, for example, she starts crying and asking why they're so mean. Usually only happens for a few seconds and sometimes Played for Laughs before moving on.
