Summary
Red Hood narrowed his eyes. Again, Nightwing couldn’t see his expression, but that was kind of the point of the helmet. “What do you mean, history repeating?”
“Robin, 15, running away after a rough case. Only clue he left? A note about family.”
Jason stopped himself from flinching, but it was a close thing. Goddamnit, yeah, that hit a nerve. Fuck Dick for that - this wasn’t close to the same thing, ok? No way had he driven Tim off to meet the same fate Jason had.
Right?
---
When Tim disappears after fighting Red Hood in Titans Tower, Dick naturally blames Jason. Jason doesn't want to believe it, but the evidence is pretty convincing. Dick wants his youngest brother safe. Jason doesn't want a kid's death on his hands. Together, maybe they can save a wayward bird and bring the family back together.
Meanwhile, Tim is feeling pretty great about his progress in tracking down Cass. It sucks he had to ditch the others to deal with the Red Hood situation alone, but Batgirl needed her Robin. Jason was annoying, sure, but he could chill out for a minute while Tim went to kick Deathstroke's ass for messing with his sister.
The note he left explained all that, right? Right?

Summary
Bruce was starting to understand the jokes about him and adopting strays. But it’s not like he ever went looking for kids to adopt. They just sort of… appeared.
Besides, the neighbor boy clearly had no one, and Bruce could not in good conscience let that assassin girl go back to parents who had treated her so badly.
If that meant Bruce adopted two more kids, so be it. It’s not like he didn’t have the room.

Summary
Once, there lived a little girl with no name to call herself, who knew but a few things; and she loved them dearly. She knew the body, her father, the trainers, the room, and the sky. In her small world there was no room for hate. To hate was to give up one of her precious few, and if she were to do so, she thought she would go insane. So instead of hate, she learned to love, Love the damp smell of mold after a heavy rain, love the rough hands of the trainers as they sent punches that threw her across the room, love the knives, the guns, the punishments for noise. She was determined to survive, so she grew to love the pain. To say that she loved all these things, did not mean she did not favor some over others. She liked the teachers with pencils and dances over the ones with swords. She liked the light in the window more than she liked the darkness of the corners. But most of all the girl loved father, until she didn't.
