There had been many stories where Wally West returns from death in the Young Justice universe, but none that seemed to really handle the concept well.

To me, it would make sense to make a story where the team discusses their best moments with Wally and then how their lives have been without him. Then, they could find some way to explain the Speed Force;

Basically the afterlife for comic book speedsters.

In some way, they have to travel inside it and get Wally who has been trapped in there since he gave his life to save the world.

I DESPERATELY wish to see something like this or maybe suggest it somewhere if you're so kind.

Wally and Artemis were perfect with each other!
