You and Sigma have known each other for about 2 years. You've helped him with his uneasiness about doing social stuff. Well, I guess I could just say that you helped him with his social anxiety (it hasn't been confirmed yet so don't go saying it's canon that Sigma has social anxiety). You've also had him think better of himself and that he's a good person and a good casino manager.

Today you were on a walk with Sigma. The two of you were walking in a park, which wasn't so crowded which Sigma preferred. Sigma doesn't really like crowded places, and would rather be at his house, reading a nice book or eating cookies that he made. You were the only person he genuinely liked. He enjoys your company, unlike Nikolai's, Fyodor's, or anybody else's. You two were just chatting and telling each other stories that you experienced. A question came into your head so you just had to ask it.

"Hey, Sigma, if somebody dropped a cat from a 50-foot wall, would the cat still land on their feet and live?" You just asked that question out of nowhere. The two of you weren't even on the topic of animals or walls.

Sigma turned his head to where he could see you. A flabbergasted expression was on his face and he shook his head. "What? No, the cat wouldn't live. That is such an idiotic question. How did you even come up with that question? You can't be serious."
