Cactus juice.
Someone had given Sokka cactus juice at the king's party in Ba Sing Se.
Cactus juice. A potent hallucinogen.
Which meant that now, back in the sleeping quarters, Sokka was going through every possible emotion imaginable. Hallucinating, alternating between being giddy, hopelessly confused, and just overall... weird.
It was like being drunk, except with far more confusion.
"It'll quench ya! Nothing's quenchier. It's the quenchiest!"
He declared proudly, holding out a cup of the stuff with a wide grin.
Lying flat on the floor, he lazily swayed from side to side as if the ground beneath him were gently rocking. Every now and then he'd giggle to himself for absolutely no reason before staring up at the ceiling with complete fascination, as though it held the secrets of the universe.
Whatever had happened at the party, he was absolutely convinced everything was perfectly normal.
He was definitely going to have one miserable hangover in the morning.
