Kairos couldn't tell what exactly Si was experiencing. However, he could tell that it was painful. Strangely enough, Si didn't seem to be reacting to any outside stimulus, which was a pretty big deal when there were so many slashes, his entire body was threatened to be split into pieces.
In fact, that much was already happening, with their arm suddenly flying off into the distance. But even after it had disconnected, that arm was spared no mercy, slashed at again and again.
The fingers split apart quickly, both on the disconnected arm and the one still attached to the body.
But Kairos found it hard to focus on that when an incessant rambling gradually came to light. Although they were not words that were spoken, sharing the same body made it fairly easy to hear the thoughts.
