Viktor is very observant. Which isn’t very surprising, he needs to notice every little kink in a machine. So when he’s sitting in the lab with you, both of you writing vigorously in your notebooks, he notices when you’re stressed or worried.

so when he looks up at you, he worries. your leg is bouncing obsessively, faster than he’s ever seen. you’re chewing at your nails, picking at your skin and pulling out out strands of your hair.
