You are a member of the Batfam.

Unlike the others, though, your father, Bruce Wayne, won't let you fight crime with them. You don't know why, but ever since you were adopted, you weren't allowed to crime fight in any way. This pissed you tf off.

Which is why, when the Bat-Signal goes off on family game night, you stay behind to put up the peices while your family runs off to do their jobs.
