Leo had the feeling that their 'They kept us alive' was similar to how Jerusalem's Lot was 'No big deal' for him. Nevertheless he doesn't pursue the subject, not wanting to hurt Zuko's feelings.

All he can think of saying is: "You never know. Maybe something good will happen." With a sheepish shrug, Leo serves more soup for guests, a small smile on his face. He hoped the best for this guy, he really did--

--wait, who even was this guy? "Also, uh, what's your name? Sorry, I didn't introduce myself. I'm Leonardo Watch. Nice to meet you." He begins to raise a hand, though stops; what if he doesn't shake hands? Awkward, much.
