It seems like, separate of everything else in this lab, Jayce has brought his very own personal source of perpetual energy. Another thing on the list to get used to, but...not a bad thing, either.

The sudden hand at his back, on the other hand, needles Viktor in a place that's never quite healed. A hand darts up to swat at Jayce's - but the strike is pulled, and the regret is immediate on the tinkerer's face. He knows it was innocently meant.

"Sorry," he mumbles softly, fighting back no more as he is guided to a seat.

"You can measure this one, then add two inches. I mis-set the height when I made it."

He pauses a moment, considering Jayce's comment, before adding: "...If it weren't for my cane, I wouldn't be much of anywhere."

Another little joke, self-depreciating.
