Jay, Gloria, Manny, Joe, Mitch, Cam and Lily apparently weren't invited to attend Frank's wedding (despite it being held in Santa Monica), which seems highly out of character for a family that is so close-knit and spends so much time together. Also, why is Frank's wedding even being held in the Los Angeles area when he and his fiancé both live in and are from Florida?
