Jayce is squeamish and even someone who isn't squeamish would be hard experiencing seeing their loved one go through something rough. So he focuses instead on his healing, he focuses on Viktor's hand and on the steps they have to take in order to get past this. He hasn't gone into shock, he's still alive, so far so good.

When Viktor's grip abruptly loosens, Jayce grips it tighter, his large hand contains all of Viktor's hand in a second, fingers holding at his wrist. "Viktor!" Jayce's healing only gets hotter where it touches him and he tugs at him, a warning, a reminder. Something to ground him to this place.

"Runes next, we have a plan. Ignore it. Stay focused." His grip on Viktor's hand and chest are hard enough to hurt, but he is holding onto him however he can. "It's time to crank it, V. Remember?" Jayce is afraid of him drifting. "Crank it."
