Thinking about it was simply similar to trying to catch air. It simply didn't make sense and in the long run was futile. Although Cyrus may not have known it, but at the moment, the fact that he was still up and his feet and able to talk, much less walk around was a huge feat on its own. Shaw of course being the one the most concerned about this Cyrus's achievement could not lay it to rest quickly enough.
"I get it if he has some resistance to my poison. Granted I have never met a human whose body was able to combat my poison attack before, I'd give that a pass. But total immunity?

And here he is...this big load of a human, standing and yapping on about how ineffective it was against him?!!" Shaw thought as he glared at Cyrus make weird movements in and around the octagon.
