One of them had fallen already. Draco took a shaky breath; he was going to die. He was going to die a painful, fiery death in a room that must reveal itself. He was going to die and he was scared.
And then Potter flew past him, hand outstretched. Draco reached but retracted quickly; Potter was too far and the mountain of flaming junk had shifted. Then, again, Potter flew past. Draco reached and pulled himself onto Harry's broomstick.
As Draco held onto Harry, relief swept over him. He wasn't dead. He'd been rescued by Potter; saved by someone he'd learned to hate.
"I'm sorry," Draco whispered. "I'm sorry," he said again, desperate. "I'm sorry, I'm sorry, I'm sorry."
They'd burst out of the Room of Requirement before he'd even begun to feel as if he'd apologized enough. He'd been horrible to Harry and, still, Harry had found it in him to go back and rescue him.
Draco ran off as the golden trio dealt with the Horcrux.
A/N: I just saw Harry Potter and the Deathly Hallows Part 2. It was amazing!
I was immediately inspired to write this after Harry rescued Draco.
