We don't know yet, but will within the next several months. prometheus thinks powergirl is supergirl. I don't think so as Arion said peegee's mother would need her in the near future.... I am confused. One of my friends was saying peegee could be the daughter of linda and superman from supergirl...
But that's the kind of stuff everyone is talking about...continuity has been flung out the door recently at DC...and that doesn't happen by accident...
