Azula and Zuko are sat drinking tea, with their father. As they both take a sip, Zuko makes a slight face of disgust, and whispers to Azula.

Zuko: "Lala... Does your tea taste weird too?,"

Azula: "Yes! Now shut up and drink before you get us both in trouble, Zuzu..."

Zuko drinks all of his, but Azula only has a few more sips and discreetly empties her cup in a plant pot.
