How could Roy allow him to leave though!? He had been forced to act, at least he had to make a clean job so that he didn't startle the snakes in the bushes.
Otherwise, either the situation would get even more complicated and messed up, or the snakes would all start running away as their lives would depend on it.
No one would stay behind knowing that their plans had been revealed, or that someone was trying to mix things up and work against them.
That would in fact be the least of his worries, as he would have to firstly think about the reaction of Earl Clark if he found out about this.
For that reason, he had to make sure that nothing that happened in there escaped the walls of this room.
Furthermore, he wasn't fighting alone, with the stealthy Master being taken down by Kate, the two beasts that had attacked him were perfectly clear and ready for their next target.
