Caduceus can't help but smile as he listens. He doesn't exactly have a lot of experience with what Mercy's talking about, but it's kind of nice to listen to her. Reminds him of his sisters, and he misses them.

He notices the blush as Mercy goes on, the way she rambles a little, the way she's very free with praise about both men.

"Have you told either of them this?" he asks mildly. Seems like a reasonable step.
