Everything Emiya said was completely true, even if Mira played it off. He only extolled a factor of her character he himself witnessed, and noted that it was a great quality for a leader to have; the ability to give a shit. As for Yasutora, Emiya already met the mountainous man himself, and had heard of his own actions, and how he fought on the front lines against Tiamat. Coincidentally, that was something Emiya failed to do himself despite being one of the catalysts for the Goddess' revival. The respect for the man went unspoken, as it was an immutable fact of the world; His actions spoke louder than their words ever could. The kiss was an unexpected touch, and one Emiya couldn't reciprocate in the moment, as his wink was merely an amatuerish attempt at hinting that there was more to his words, so it was his own fault. The more practical gift of the communication scroll was the clearly more appreciated of the two gifts, as it was clear Mira wanted to be kept in the loop, while the former gift could have any number of nebulous reasons, none of which were important right now. As Mira left he gave her a simple reply.
The words were mockingly used as a joke to ease the tension clear in the air, and Emiya hoped it would put a skip in Mira's step as she casually returned to an active war against an exanimate army. And in response to Mira's departure, Emiya continued his beeline for the Spider's lair, just as resolved for answers.
"For someone who hates praise, you sure do think highly of yourself, and me for that matter. Genocide? I'm neither worth that much effort, and I mean no offense, but that might be just a little bit out of your depth. But don't worry about me. If anything happens, you'll be the first one I come crying to for help. Unlike Merlin you won't gloat about it until the end of time, and unlike Solomon you might actually get involved, haha."
