All the women inside seem to be in an extensive need of some rest, as a lot of them were just resting there like corpses, without doing anything, and just bearing the attacks of the soldiers.
Roy felt a sudden urge to go and vomit outside, but unfortunately, he couldn't break his character in there.
It was extremely difficult to create the current situation, and he even managed to keep control over his body when he drank that piss, there was no way he was breaking his character now.
But at the same time, none of these women managed to even cause a slight reaction in him. In fact, he felt like they were just pitiful souls, that shouldn't be touched.
And if the look wasn't enough, then just the idea of all the juices and diseases that might be flowing around made him feel extremely disgusted.
He felt that if he stayed there to watch this scene more, he might even have thoughts that being an impotent was better than having fun with these ladies.
