Short answer, Kilo is fine, I was just overthinking.
For context this is the original post. I asked Kilo how he felt about the discussion that night and he told me that he was mostly talking about other people (except me) hurting others. He said I was fine the way I was and that he was not hurt by the debate. It was nice to hear that I was special to him (but apparently not special enough to be immune to concussion symptoms). Thank you to all who replied to the previous post and encouraged me to talk with my friend.
