Viktor has a strange relationship with physical touch, that much was clear. On one hand, if he needs to focus on his work, he may shrug off any attempt to initiate more than a quick squeeze of the shoulder or hand. On another hand, he’s very touch-starved. He loves your fingers in his, you've found to notice. If you pass him, he’ll catch your hand and press his lips to your knuckles.

A little downside was when he got too stressed to think, where his brain refuses to compute and the feeling of someone else touching him makes it 10x worse.
