Replacement
"Replacement" had always grated on Tim. For starters, he'd never wanted to replace Jason Todd in Batman's life or Bruce's, had only become Robin as a necessity. But mainly, it had always been perfectly clear to everyone—except, apparently, Jason—that Tim hadn't replaced him, in any way. Jason had left a gaping hole in the family and Tim had never been enough.
Then Robin was taken from him, handed to Damian, and he got it.
He'd never legitimately tried to murder the little brat, but then he and Jason were very different people, weren't they? (That was the problem.)
Why does every single bat except maybe Cass have self-confidence issues? Seriously.
Anyway, I love Tim and Jason's weird brotherhood thing where Jason never lets anything go and Tim's caught between hero worship, fear for his life for legitimate reasons, a need to make actual connections with people who understand his life, and frustration because, well, Jason and the shadow he casts and his personality.
I also love Tim and Damian's relationship and how it weirdly mirrors the above, but with obvious and major differences still.
Basically, these idiots need to appreciate Tim Drake more, the idiots who publish this stuff need to appreciate Tim Drake more, some idiots in the fandom need to appreciate Tim Drake more, and someone needs to give the self-deprecating, caffeine-addicted idiot a hug or five.
