Flirting?

I challenged your Spy Pengling to a foot race earlier. Because you got tired of losing to me? Ouch! What if I've been letting you win so I could see you smile? Cute. But I don't believe it. There are easier ways to make someone smile. Easier than losing a footrace?! Oh I think you're a woman of many talents. What are you implying? The artwork that appeared in my lab the other day... Oh that-- "A Study in Parhelion Red?" I assume you had something to do with that? That depends. Do you like it? It's beautiful. Like the person who gave it to me. If I didn't know better, I'd say you were flirting with me. Do you know better? I...don't know what I know anymore...Not when you're looking at me like that.
