Altar Egos

S6, E25: Fred is unsettled by the fact that Jackie turns to Dan, and not him, when she needs help from a man. Upset, convinced that Jackie has feeling for Dan, and half-drunk, Fred confronts Dan, takes a swing at him, and tells Jackie that maybe they shouldn't get married, but offers no explanation. Dan tells Roseanne, who tells Jackie what is really troubling Fred, and they both have a good laugh at the idea. Clearing the air paves the way for Fred and Jackie's wedding.
