The season finale ends at the altar, but who is the mystery bride?

Dave finally makes a decision: The season-long plot involving Dave Dash/Dave Williams seeking revenge against Susan and Mike for the car accident that killed his family finally came to an end. Dave headed up to the lake to kill M.J. to make Susan suffer the way he had. But Mike found out what was going on, and alerted Susan. After a struggle, she found herself tied up and waiting for Dave to crash his SUV into Mike's truck to presumably kill M.J., who was in the back seat. But at the last minute, Dave had a vision of his beloved dead daughter, and sent M.J. safely out of the car. The crash still happened, but M.J. and Mike were fine.

About the show: The series follows Mary Alice Young (Brenda Strong), who commits suicide in her perfect house in a lovely suburb and then, from the afterlife, narrates for viewers the lives of her family, friends and neighbors on Wisteria Lane. Her circle of girlfriends include Susan Mayer (Teri Hatcher), who finally married the love of her life, Mike, only to lose him because of her anxiety issues; Lynette Scavo (Felicity Huffman), who struggles with running her family's restaurant and raising a slew of children; Bree Van De Kamp (Marcia Cross) -- Martha Stewart on steroids -- who tries to keep up her image of perfection while everything crumbles around her; and Gabrielle Solis (Eva Longoria Parker), the high-maintenance ex-model who divorced her first husband, Carlos, to marry the town's mayor. After a tornado on Wisteria Lane killed the mayor and left Carlos blind, Gabrielle remarried Carlos, her true love.

Then there are the men: Mike Delfino (James Denton), a plumber who divorced Susan, his scatterbrained wife and mother of his child; Lynette's adorable husband, Tom (Doug Savant), who always stays by his wife's side despite many challenges; Gabrielle's husband, Carlos (Ricardo Antonio Chavira), who adapts to life following an accident that left him blind; and Bree's husband, Orson Hodge (Kyle MacLachlan), who helps Bree keep the many secrets that uphold their image as a perfect family.

"Desperate Housewives" airs Sundays at 9 p.m. ET/PT on ABC.
