Ah, that was something he could relate to, Sybil's determination to do something for others in face of a greater threat rather than nothing. Priests prayed, Cardinals schemed but Cesare Borgia took action to resolve problems. That had always been his strength, and while it was not the same as Sybil being selfless for the sake of others, at the expense and risk to her own person, it was something he appreciated. Though let it never be said Cesare did anything for the greater good.
He said nothing of it though, finding no use to congratulate her on her humanity or raise a philosophical debate on the nature of the human condition. He hadn't the mind for it when he was at his healthiest, let alone now while reduced to shivering in a sickbed. Recalling the water in his grasp, he drank more of it, wondering vaguely when the aspirin would begin its work.
"The boy?" he queried. "Young, hale, vibrant." he closed his eyes and thought back to Cuthbert and how he'd appeared to Cesare. "He showed no signs .. not that I recognize, but I was not looking for it." And he could very well be wrong, as such. He wasn't a physician, and unless one was coughing up blood or fainting from fever he was fairly oblivious to illness. Cesare let the silence settle around them for a moment, then met her eyes with as much clarity as he could muster.
"Go to him. I'll not see him die on my account." He didn't know the boy well, but youth held more value than the old.
