You, the beta trolls, their dancestors, and ancestors got invited by Dave to a party.

Gamzee: Is getting high on sludge. Kanaya: She's talking to Aradia and Nepeta. Tavros: He's talking with Equius' Dancestor, Horuss. Equius: *He's sitting on the couch and talking with Damara (Aradia's Dancestor) Terezi: She's Drinking from her cup while talking to Porrim (Kanaya's dancestor). Sollux: He's Cleaning his glasses while sitting on the couch in silence. Feferi: She's talking to Eridan about the sea. Karkat: He's talking with Dave and Rose. Virska: She starts talking With Kanaya and Terezi. Kurloz: He's drinking silently while talking with Mituna (Sollux's dancestor).

The ancestors are mostly talking between themselves.

You're sitting on the couch silently, enjoying the music.
