Hello,

I saw a part of a story of (probably a JL story) which I found interesting and I would like to ask the name and probably for a short summary of the story:

In this story the JL is in a house, where a mother with a child is.
Batman goes to the child, takes one toy and child wants to have it back, so the toy breaks and mother makes the JL leave the house.

As far as I understood from the context, Batman did this to look if the child got Superpowers.
If I understood correctly the father got superpowers during a trip and the JL knew it, but they didnt know that he took also the child with him.
