"What Did You Séance?" is the third episode of Detention.
During the school's Disco Daze dance, Shareena and the gang perform a séance. Meanwhile, Emmitt and Shelley (who thinks they're on a date) wait for aliens on the school roof.
- Shelley's rant about missing the dance is an homage to Sally Brown's rant in the Peanuts comic strip originally published on November 3, 1962 (adapted in It's the Great Pumpkin, Charlie Brown).
