Bruce walked away from the warehouse. He refused to play Red Hood's game. Jason pulled the trigger, the Joker fell, and Jason's laugh broke into a cackle. That was expected.
The building exploding under them wasn't.
Bruce crawls from the rubble desperately looking for Jason. Not again. Not again. Not again.
He does what he's rarely ever done, "SUPERMAN!"
Strong arms wrap around him, staring at the collapsing rubble with a frown, listening to Batman, no Bruce, fall into a flashback. "Jay, Jason, please, not again not again."
It's difficult to x ray in Gotham, lead and curses making every structure a little obscure to his vision, but he spots the two...bodies.
He digs them out, setting the grinning joker aside and carefully carrying the body of Jason Todd out to Bruce. The skull is cracked open, body badly ripped into by shrapnel, and carries them both to the manor.
Superman lands in the Cave, touching down on the stone floor as gently as he can, not daring to jostle his cargo.
He walks slowly to the medbay, as slowly as possible, not wanting it to be over just yet.
But all too soon, he's standing in front of a bed, and bows his head. Bruce touches down on the mattress first, Jason after, and Clark indulges his friend, encouraging them to fall in towards each other.
He pulls his hand back, but not so far that he is no longer touching Bruce. He allows his hand to stay on Bruce's leg, not ready to let go yet.
Abruptly he finds himself to be kneeling, pressing his head against that same spot, clutching onto Bruce as his cries fill the cave.
He'd tried— he's tried to convince Bruce to leave.
But no amount of assurances would make him allow Clark to look for Jason alone.
He screamed, he crued, delirium took over, and Clark could not bear to deny him. He could see the truth. Bruce didn't know, he probably wouldn't have cared, but Clark knew.
So he let Bruce stay. He pulled Jason from the rubble and placed him in Bruce's arms.
Then he picked up his best friend, and flew back to the Batcave.
Bruce weeped, stroking Jason's mangled skull, whispering apologies over and over until he choked on his own blood, whispers turning to gurgles, apologies morphing into deprived gasps for air, then it all stopped.
Clark knew the explosion killed Bruce.
So he gave him a few more minutes with his son, rather than the chaos of an operating room, and pointless efforts to save a man whose death certificate was already stamped and dated.
