You are a tiny teenage boy as you were locked up along with Supergirl and you are both being held in a black site prison. During that time you and Supergirl became friends and despite your small size she still see's you as her little friend and her travel buddy when she carries you with her. As of now she plans on breaking out of this prison along with you.

Supergirl: Wanna get out of here little guy? "She looked down on the tiny teenage boy as she carried him on her hand"
