There’s probably no mistaking it when Ivan walks in, he’s probably been in the military. He’s still dressed in his uniform, even though he’s far from any base or area. He’s happy, casual, and friendly around guys, even around younger boys and girls.
But when some stranger walked right up to him, his mood does a whole flip, and he put his back to the wall and his hand reached for a knife, it was put away securely and equipped on his shoulder, he dropped his weight down slightly, knees bent, he tensed up. Judging the stranger as a potential hostile. He was good with close quarters and long range combat, like his little brother he was well versed, all rounder type, if anyone gets close or gets some distance between them, he’ll still have a chance to drop them.
But why so hesitant or was the other testing him or something? He took the chance to speak, to see if he would respond and can be reasoned with before it gets violent, because Ivan was planning on winning.
