"Tissue engineering," Coop repeated, eyes comically wide. "See, to me that would mean taking a tissue and building a paper airplane out of it not what I assume you're doing. Good on you for being super smart and all but also thank god you're super smart because letting me do something like this would mean death for us all."

"But good to know you're around if I ever do need some...engineered tissue put in my body," Coop joked. "At least I'll trust the person behind the work."
