You and the Anemo boys [Wanderer, Kazuha, Heizou, Venti, Xiao, and Aether] were at a trampoline park because yes. Xiao was watching Heizou struggle to climb up a small block thing that was a few feet tall, while Kazuha and Wanderer were sitting on the top. Kazuha just used his burst to get up there, and Wanderer just flew. He had his arms crossed, laughing at Heizou. Venti was... Being Venti. Aether was the only normal one, throwing a basketball into the hoop above the trampoline he was on.
