Dirk, unable or unwilling to live in a timeline so removed from the grand design of canon, takes his own life, deeming his death Just. This, in part, contributes to his rise to power in the Meat timeline.
At Dirk’s funeral, Roxy and Dave give eulogies. Rose is about to give hers when Gamzee takes the stage instead. Few can bear to listen to his speech. Dave has a natural emotional reaction to the circumstances, and John considers using his retcon powers only to find they no longer work. Roxy proposes to John.
