Blake and Sun "lose track of time" before class and have to rush to catch up! The first episode of the Lust Dust timeline, Tardy is a "Silver Age" RWBY smut (occurring before the tournament events of season 3 reach full swing). As such, it has access to many characters introduced after the "Golden Age" fics of Season 1 and 2, but without as many post-apocalyptic tones of the "Modern Age" fics.
