Katara knew Zuko normally woke up earlier than everyone else, forcing Aang to start training at sunrise. But she didn't know just how early until she snuck back from her secret moonlight bending practice. When she returned to the Western Air Temple atrium just before twilight kissed the sky, the glow of a small fire caught her eye. A dark figure sat next to it, causing her to freeze. Upon recognizing it was Zuko, she snuck closer and hid behind a column to watch him. Someone had to - she felt like the only one who remembered he was untrustworthy.
Still as a statue, save for his chest falling and rising in deep breaths, Zuko monitored the boiling teapot. She watched his hands as they gingerly grabbed the ceramic pot, realizing that she'd only ever watched him wield them as dangerous weapons. This delicate ritual was clearly familiar, as Zuko didn't have to look at the cup clasped in his long fingers before tipping the pot.
"Will you join me or are you just enjoying the show?" His hoarse voice interrupted her thoughts, forcing her gaze from his hands. His face was set in indifference, but she could see his amber eyes dancing with amusement in the fire light.
"Don't flatter yourself. I'm just making sure you aren't plotting to kill us in our sleep," Katara spat out, striding past him towards her room. She fought the urge to steal one last glimpse of him before she turned into her room.
