Name Game.
Hey! I just wanted to drop you a note because this is confusing...!
In the Guy+YJ+PG scene, I keep having Power Girl refer to herself as Kara and I just wanted to explain that real quick.
Power Girl's Kryptonian name is Kara Zor-L, so that's how she refers to herself, especially considering she spends most of her time as Power Girl anyways. Her civilian name is Karen Starr, which Guy would know her as. That and Power Girl.
