So Seppuku wanted to go out for a walk by himself one day. I let him, forgetting that even his subconscious is trying to end him. He eventually came to some sort of street and tried to cross without looking for cars. He probably would have been hit if Dust hadn't been there to grab the rope around his neck and pull him back.
Dust actually yelled at him for this. "What have you got a death wish or something!?" Seppuku said "Uh-um. Thank you for saving me." Dust said "Oh. Your welcome. Sorry I yelled at you." They had a little conversation as Dust walked Seppu home. When he left he just said "See you around, Death wish."

Seppuku: He actually left me his number too.

So that's that.
