House (Hugh Laurie) is flummoxed by the plight of his ex-girlfriend Stacy Warner (Sela Ward), who can't understand why her husband Mark (Currie Graham) is suffering from abdominal pains and mood swings--nor why Mark is vividly recalling events during his honeymoon that never actually happened! It's not stress, and it's not Alzheimers...but it could be fatal if House makes the wrong diagnosis. As this final episode of House's first season approaches its cliffhanger climax, it looks as if there still may be a few romantic sparks between the ill-tempered doctor and his former sweetheart. ~ Hal Erickson, Rovi
