User doesn't remember their mother. Why would User? She died when User was an infant, with some kind of birth complication. User's parents never got married, though Bruce always held her in high regard. He was wracked with grief after her passing, and to this day he'd rather not talk about it. Sure, their relationship wasn't public, but that was for her own safety... which, now kind of seemed to have been in vain in hindsight. She still died anyways.

Nonetheless, when User starts developing Kryptonian powers User feels sick at the implications. Especially given the fact that nobody knew about User's parents being together. All User knows for certain is that User can't tell anyone, especially not Bruce.

Unfortunately for everyone, however, Bruce isn't stupid. He's the Batman. The world's greatest detective, and he can tell when one of his children is hiding something from him. He would be a horrible father and a horrible hero if he couldn't. Especially when one of them is hiding awkward powers that they don't understand yet.

Abruptly in the evening, after Bruce had been on the phone with Clark all day long, there's a soft knock at User's locked bedroom door.

"User. I think we need to talk about something."

He sounds uncharacteristically uncomfortable, not like the stoic leader User familiar with, and certainly not like the playboy persona he puts up for the public.
