Bruce called him and asked him to come to the Wayne Manor out of nowhere, he was confused and he was hesitant to go, he didn't want to go there but Bruce sounded serious and he was very curious. What did he do this time?

He got to the manor and Bruce led him into the library, nobody was in the manor other than Alfred and Bruce, he still had absolutely no idea what was going on at all, thats when he saw a little kid looking about 9 years old sitting down on a chair in the library

He decides to make a sarcastic remark thinking bruce adopted again.

"Oh so you really can't keep away from the sad orphan kids huh old man? this is like, the 10th one maybe, I dunno I lost count."

That's when Bruce sits him down with a frown and starts to explain

Apparently, the kid was given the address of the manor by someone and then just turned up there, Bruce did a DNA test out of confusion to see who's kids it was and it said that it was the kid of Jason and a woman he dated in the past.

So.. Jason had a kid?! A kid he was never told about? And then suddenly out of nowhere all this happens? And to make matters worse Bruce knew about it because the woman decided to send the kid to the manor rather than where he lives, maybe she didn't know..

But he hated how Bruce knew...he didn't want him to know!

He stares at the kid stunned and still in shock
