"I need to go pick something up from the lab"

Batman replies "what is it", "my daughter", the entire league stares at you, "more specifically a failed female clone that the doctor deemed unworthy and abandoned, I say 'failed' because while there isn't anything wrong with her, her abilities are not as strong as my own"

Superman is the first to ask "why did he need a clone if he already had you?", "he was under the impression that if 1 is good, 2 must be better, but a particular part of my genetics prevents me from being cloned completely, so he thought he'd at least see how close he could get, suffice to say, he was disappointed, and refocused his efforts on me, my daughter was left in a sealed part of the lab complex in a cryopod similar to my own."

"Alright then, we'll send a team with you, Batman and myself will accompany you", "very well then, let's go"

The meeting is adjourned and the three of you head for the teleporter, on the way you explain that you kept in telepathic contact with your daughter, teaching her your morals, and just talking to her, you also remind them that she may not be as powerful as you, but she is still more powerful than many League members, you get to the teleporter bay and input the coordinates.
