"It's no good, Barry," Wally said to his uncle as he attempted to grab the boy's shoulder, only for his hand to pass right through.

This is it then, Kid Flash thought to himself. I'm going to die. But still he kept running. He ran for his family. For his friends. For the Team. For Artemis. He kept going knowing that if he stopped, the world was doomed.

"Artemis is so gonna kill me for this," he continued. "And don't even get me started on mom and dad."

"Kid?" Flash called out to his nephew, afraid of what was about to happen.

"Just tell them," Wally replied bluntly. "Okay?"

"KID!" Barry shouted. And in a flash of light, Wally West was gone. Before he lost consciousness, there was only one thought in his head: I'm sorry, Artemis.

"They did it!" M'gann shouted as vortex disappeared and the six superheroes ran (or flew in the young martian's case) over to the two exhausted speedsters kneeling in the spot where the chrysalis of The Reach's MFD once loomed.

"It's Over!" she cheered as she helped Bart to his feet.

"Congratulation!" Aqualad said as he walked over to the Flash to do the same. "You have s – "

"WAIT!" Artemis interrupted as she looked around, trying to keep the fear out of her voice. "Where's Wally?"

"Artemis," Barry began as he walked over to the young woman, mentally preparing himself to say to his nephew's girlfriend the words that would shatter her heart and torment him for the rest of his life. "He wanted me to tell you – '

"No," she gasped as she realized what he was about to say. "No," she repeated, almost a whisper this time. Hoping against all odds that he wouldn't say what she was afraid he would say. Please don't say it, she thought to herself. Tell me he's trapped in another dimension or something, but please don't say that.

"He loved you," Barry finished as he put a comforting hand on her shoulder.

Artemis dropped to her knees in tears as M'gann raced over to comfort her grieving friend. A few feet away, Aqualad, Superboy, and Nightwing exchanged glances as they mourned their fallen brother in silence, listening to the sound of his girlfriend's anguished sobs echo across the arctic tundra.

The tranquil calm of the Arctic Circle was broken by a crack of thunder and a flash of light. Within seconds, a young redhead stumbled out of the light before falling face first into the snow. Clad in red and yellow, a quiet groan escaped the young man's lips as he lay there in the cold.
