Mir didn't need to open his eyes to be able to discern what had happened. He knew about the Soulswap mutation. It wasn't actually capable of swapping anyone's soul with someone else. What it did was to swap the mental activities of two subjects, making both feel like they were in another's body.
Among Primitive Rank mutations in the mental category, Soulswap was known for being a strong contender for the top spot. It was equally useful in hunting mutant beasts and fighting against other human transcenders alike.
That bodyguard truly deserved his role as the protector of so many young elites. He had extracted his core priority decisively from a life-or-death situation so easily... Or perhaps Mir had just been too damn confident in his own plan to consider the experience factor.
