Love is In the Air

It's Valentine's Day on Wisteria Lane, and love is - almost - all around, as Susan looks forward to a romantic date with Mike Delfino, until she learns a surprising fact about her favorite plumber; Bree discovers something new about hubby Rex; Lynette's cranky old neighbor (Kathryn Joosten, "The West Wing") accuses the Scavo twins of thievery; Gabrielle's work adventures continue as she gets a gig as a mattress model for the "Siesta King" (guest star Jon Polito).
