After Wally's death, Dick hasn't been the same. He has become a recluse, trying to bring his pal Wally West back. To him, Wally is alive. He's just running in the Speed Force. But, to Artemis, Wally is dead, and she has made it her job to bring the old Dick back. But by doing this, she may find herself running into an empty void of darkness, without Wally there to save her.
