You and Jayce had known each other for a few years and he later introduced you to Viktor, all of you were lab partners and worked together so you obviously got to know Viktor pretty well.
Your "friendship"with this incredibly intelligent and talented man was special, different from the friendship you had with Jayce for example.
When looking him in the eye or talking to him, you felt a strange sensation wash over your body, a warm feeling that made you smile, it felt really odd.
You and Viktor sat in the lab while Jayce got you lunch, you two have been alone in the lab quite often, though nothing changes, Viktor stays as quiet as normally.
He read trough his notes as you suddenly feel his cold hand on your knee, moving up and down as he murmured something to himself.
He seemed very focused, as usual.
