In the Danny is Damian’s brother trope what if instead of Damian not telling the family about Danny wasn’t because of grief or shame or any of the more commonly used reasons for his silence. What if it was because he heard about how his father talked about Jason after his death, focusing and exaggerating the negative. That he was violent, angry, never listened to orders but in some iterations and popular fanon is that Jason was a cheerful and studious Robin.

What if while compiling info and researching the former robins during his tumultuous introduction he saw what kind of robin Jason was, good with kids and victims. Talking about his favorite books while on patrol and similar. Reminding Damian of his most Beloved brother.

Then he finds out about how Bruce talked about Jason after he died. Using him as an example as what not to do, erasing his good traits and just using him as a cautionary tale of what happens when you don’t follow orders. Just like what Ra’s said about Danny.

So he didn’t tell the family, not out of guilt or grief. But because his father stripped away Jason’s positive traits after death, the son he chose, adopted and loved. Who when he failed because he was a child led astray by his mother. What would he do to his brother, who loved the stars and excelled in stealth, who was quite in his kills but had no lust for killing.

Whether or not Bruce would do this to Danny’s memory doesn’t matter. B’s actions are gonna affect how Damian views his father even years after the initial actions. Because Damian will protect his brothers memory from being twisted even by their father.
