There are rumors that if you keep him alive for 1 minute exactly somthing happens but thats nearly impossible with so many people around. Asking nicely for people to wait makes people want to do it more.
Kept him alive for 7 minutes 23 seconds before someone killed him.
Nothing.
Also went through every emote after 5 minutes.
So.. unless you guys think there is some secret plot he for now is confirmed to do absolutely nothing at this stage of the event. Make sure to spread that around to people who think of this as the second Gwen or somthing.
