He's a Proto, he doesn't have issues. He has subscriptions.
If anyone is looking for Proto after his encounter with Enzan, or even just looking for the boy, they can find him sulking in a part of the Nexus. He's got what's going to be a beautiful shiner and some nice bruises as well, and he seems to be looking for someone.
Sadly he'll probably not find the exact person he's looking for.
