I don't own Young Justice
The die hit the ground and rolled forward. Wally squeezed his eyes shut, and opened them. There it was, the deathly black, the evil black, burned into the cube with all the heat of Wally's anger and hate. Before he pulled the trigger, he looked into the hollow, empty eyes of his former mentor. The look on his face was dead already.
Of to their left, Iris clutched Don with all her strength. Dick had grabbed Dawn and Bart's bleeding, dying body and rushed them out in the earlier commotion. He had tried to get Iris out too, but she insisted that he would be faster without her, and time was one thing that Bart was quickly running out of.
Now it was just the four of them left.
Wally stole a glance at his favorite aunt, strong, proud Iris, reduced to sobbing in the corner.
He looked at the crimson puddle in the center of the room. Bart's blood. His cousin's blood. He thought back to when he had first met Bart, back in the spring of 2016. He had been nervous and talkative at the same time. Wally could relate. He had been like that one day, many years ago.
He thought of how cool he thought his uncle was when he was five. He remembered when they went out to get ice cream a few days after he became Kid Flash. The two of them had nearly eaten the place out of business. He remembered the look Aunt Iris gave the two of them when she saw how much of it they got on their shirts.
He suddenly felt sick to his stomach. His knees buckled. He was going to- to kill his uncle and mentor and father because some dice told him to? He shot his cousin? He was about to destroy a family? His family?
The gun slid from his hand and landed on the floor. He fell to his knees. What had he done? He became a monster, a villain, everything that he dedicated his life to eliminating.
He burst into tears. He couldn't live with himself. Maybe Zoom was right. Maybe Wally had died that day. Barry was already at his side, as if he had always believed Wally wouldn't do it.
"It's okay Wally. Everything will be okay. You can come home. Nobody else needs to die"
"No. One more person has to die" Wally reached out and picked the gun up off the floor. "Zoom still isn't gone. He needs to go" Wally pressed the gun to his own head.
Barry was horrified again. "Wally, slow down! We can think about this for a second!" He reached out to take the gun, but Wally shifted out of his reach.
Wally shook his head sadly "I can't slow down because he won't. And Zoom can't come back" A few last tears ran down his face. "Tell them, okay? Tell them I'm sorry. That in the end, I beat him. I died a hero".
Wallace West inhaled one last time.
There was the terrible, deafening sound off a gunshot. And then, all was silent.
A/N: I think I might write an alternative ending that's less morbid. I didn't quite realize how sad this was until I wrote it.
