I think a good way to do tag - since, you know. It's pretty difficult to keep everything straight. Treat each character's movements as a separate thread. And then whoever is "it" at the time will pick the character they want to catch? So in this case, Reborn will choose...say, Gon. And so Reborn and Gon will have a short spate of interaction. Then Reborn can choose either to switch to someone else - going into a different thread - or Gon can decide whether or not to let Reborn catch him. And then we'd establish another set of threads for a new 'it'? So the people who are not actively being chased can choose whether or not to comment on their own thread in reaction to whatever the 'active' thread is doing?
OOC first, then post.
