[ Walter's not confident in doing this but. He's fond of Wrath. He knows he cares about his Pokemon (the ones he's seen anyway). Wrath did give him a gift - a very weird gift but it was a gift - so he wanted to return that gesture. He sent Darkness ahead to get him, to lead him over to Walter; his house was not a safe place for Walter to approach, given he now knew who lived there. He turned as Darkness returned to him, perching on his shoulder and nodding to the younger Rocket. ]
FORWARD DATED to New Years Eve!
Wrath.
