She's speaking to him, he believes. Well, he sees her mouth move and her lips swing, but he doesn't hear a thing. He's too focused on said Katara's lips.
It's been a while now that he's realized his true feelings for the girl, but knows he will do nothing about it for now. They're friends. It's simple enough to ignore the frenzied beatings of his poor heart when she's there, close enough to feel, or to act as if his sleep was all peaceful when really, all he dreams about is her.
The current problem, though, is more difficult to ignore.
It's her mouth. Her lips. Painted red.
Now he doesn't really know what took Katara tonight, why she suddenly decided her naked lips wouldn't do. All he does know is that her lipstick (not even that red, when you think about it, just a little darker that her skin tone) attracts the eye on her mouth. Well, more precisely, attracts his eye.
It's pretty complicated to focus on not showing his feelings when all he thinks about now, is how much he wants to kiss those lips.
Like, really really.
Oh he keeps "listening", his eyes transfixed on her lips. But then she notices, finally, that he seems distracted, and stops her incessant blabbering.
"Hey, you listening ?"
He doesn't, but of course he can't tell her that.
Instead, he leans in slowly, and Katara sucks in air and then seems to have blocked her breathing, seeing him getting all close to her. He lifts a hand –the right one - towards the girl's face and…
Smears her lipstick across her face with his palm.
Zuko sighs. That was close.
