Depends on their fighting style really. Huge muscles can slow you down and reduce flexibility, so it has its ups and downs. Hex also uses her body to get information as seen in the previous episode. More slender types are preferable in such scenarios.

Koko really is a softie inside. The death of one subordinate has affected her so much. The betrayal and the possible death of another might be enough to "kill" her, just like Hex plans. I am genuinely hoping it is Jonah (and his rapid growth under the tutelage of the others) who foils this plot.
