Khan didn't completely agree with Lieutenant Dyester's words, but he followed his directives anyway.
It felt good to have someone watching over him during his training. Lieutenant Dyester pointed out many mistakes that Khan had started to absorb in his battle style. They would have become bad habits in the long run, but the soldier had caught them before that.
The lack of the mental barrier made Khan slightly weaker due to various undesired reactions during the battles, but he started to notice unexpected improvements after a few days.
Being emotional during a fight was a disadvantage, but learning how to control those feelings helped Khan's mindset. Moreover, his combat instincts developed faster when he used the entirety of his mind against the puppets.
