Grey and Keith decided to work out a plan, Void brought the idea of beating them up in the Faction, but Grey and Keith were against it mainly because of the fact that conflict was forbidden in the Faction grounds. There are places where they spar, but the Faction ensures that no one dies from these.
After coming up with multiple plans, the best option they could come up with was simple: Keith would head out for a mission, and Void would go along, accompanied by the two-headed snake. Once they were outside, the snake would kill them.
Keith thought it was a good plan, so did Void. Although he was a little downcast that he didn't get the chance to kill them, he was happy as long as they were dead.
