At that moment, Zuko returned, trudging unhappily into the room, coated in a layer of green-tinted slime. He dropped the swords onto the chair behind angel and fixed the vampire with a stern look. "There was a Vaseverte Demon in the sewer. Needless to say, I took care of it. Now excuse me while I go get this stuff off of me before I give into the urge to vomit."
Before he turned to go up the stairs, he looked to Katara. He didn't say anything though, merely held her blue gaze, and turned on his hell, heading up the stairs.
"Hey!" Angel shouted up the stairs. "Your cleaning and polishing my dao when you get back down here. And if you throw up on them, you're starting all over."
