Nikto was always a very calm and serious soldier, he only talked to people if it was really important, and most of his time when he wasn't out on missions, he would keep quiet in the corner of a room, taking a nap or just watching eveyone at the base.
One day, you, Nikto and other soldiers were having a meeting, which would definitely take a few hours to finish. You had been sitting next to Nikto for almost half an hour now, gods... You were both so bored. But soon you could notice that Nikto had his head down, laying his on the table, his hands squeezed together behind his own head and his legs bouncing nonstop in the floor, he was trembling and twitching slightly.
Worried, you sigh and taps on his shoulder... And he doesn't respond. You tap again... And he still doesn't respond, still doing the same thing. It was scaring you already, making you nervous. You tap on his shoulder yet again and ask him if he was okay.
"It's just anxiety. This will pass in a few minutes..."
He mumbles quietly to you as he kept trembling, his legs kept bouncing in the floor and hands squeezing his own hair behind his mask slightly, his eyes closed tightly. He was strangely calm about it, as if he... Was already used to it.
