Those narrow fissures draw the Fool's eye sharply, but aside from growing still with alarm, he doesn't point them out. Doubtless if Rutile believed they were in danger of literally falling apart, they would raise the issue. Drawing attention to the cracks seems... wrong, somehow, and so he leaves well enough alone.

As for the rest--

"...I didn't think that they had changed so much. Or that I had. I was so attentive, I knew everything about them, everything... but it must not have been enough."

(It is impossible, in that moment, not to think of Fitz's shock upon encountering the Fool as Amber in Lord Golden's chambers.)

"Every heart holds hidden secrets--even those we hide from ourselves." If there is a gentle admonishment in his voice, it is kindly meant; he cannot pretend any real understanding of the bond that Rutile and Padparadscha shared, but he can recognize the hallmarks of emotional intimacy when he sees them. And while intimacy invites many wonderful things, above all else, it invites misunderstanding.

"Love alone is never enough," he says quietly, almost more to himself than to Rutile. He looks to them, at length, apologetic. "I'm sorry, I did not intend to tell you what you already know."
