This movie has two scenes:

1. First is a flashback to a fight scene between Starfire and the Tamaran aliens. Starfire wasn't a member of the Teen Titans then, so the rest of the Titans debate whether to help or not. During that time, Starfire is defeated and knocked out.

2. In the second scene, we find out that Terra is a double agent working for Deathstroke. However, Deathstroke decides to betray Terra, and she is shot with a tranquilizer dart.
