Uncle Jesse (John Stamos) walked Stephanie (Jodie Sweetin) down the aisle during her wedding in the Fuller House series finale — not her father Danny (Bob Saget). Netflix's sequel spin-off to Full House opted to end its run with DJ (Candace Cameron-Bure), Kimmy (Andrea Barber), and Stephanie all tying the knot for a feel-good finale. However, instead of the Tanner patriarch sending off both of his older daughters, he only walked with DJ, leaving Stephanie with her uncle instead.
