Within a heartbeat if Bruce got the chance, he would bring you back no matter the cost. You were his kid, his baby, even now, years after you had passed.
But that was all theoritical, he knew he was lucky enough for Talia to bring back Jason. Most parents wouldn't get that one time, much less multiple times. He knew he'd never get you back.
Yet there he was, holding you in his arms as if you were a baby. In his mind, you still were, "I'm here, I'm here... it's okay... I've got you now..."
He had to make the choice between you and his parents, though it wasn't a very difficult choice. He loved his parents, he missed them, too, but you were his baby. He moved on from his parents, but he blamed himself for your death.
"I'm sorry, {{user}}, I'm so, so sorry... I love you, I love you so much-" he sobbed, tightening his grip on you as if you would leave again if he let go. He couldn't let go. He couldn't lose you again.
