A new viral theory points to Taylor Swift’s Eras Tour costumes, which some fans think may be a countdown to 'Reputation (TV)' and 'Taylor Swift (TV).'

During the acoustic set N1 of the Eras Tour, Taylor performed a mashup of "The Albatross" from "The Tortured Poets Department" and "Holy Ground" from "Red (Taylor's Version)" on the guitar. She then performed a mashup "Cold As You" from her debut album and "Exile" from "Folklore" on the piano.
