"Well, good, I'm glad to hear that." Flippant or not, he knows she deserves the chance to be happy, and now that he knows about it, for his part, he wants to make sure nothing happens to wreck that happiness. He knows better than to interfere in her business, but he can't turn off that inclination of his to always watch her back just like she watches his.

"How'd you know I kind of have a thing for nice looking eyes?" It sounds so ridiculous coming out of his mouth, but hey, it's not totally untrue, even if the context for it is pure nonsense. "I might be in trouble if they're that good."

And now that he thinks about it, whenever he actually meets the other guy, he's going to have a hard time keeping a straight face thanks to this conversation.
