In 2013, Tracy Quartermaine rescued Luke Spencer from being poisoned by Helena Cassadine, and they two reconciled when Luke proposed (via Soap Central). The happy-go-lucky Luke seemed to return to town with a different personality though, disregarding his daughter Lulu (Emme Rylan), putting the moves on the young Kiki Jerome (Kristen Alderson), working with mob boss Julian Jerome (William deVry), and trying to blow up the Haunted Star. Tracy remained loyal, however, and the two were married at the 2014 Nurses Ball. Residents of Port Charles began to suspect that “Fake Luke” — or Fluke, as he was dubbed by viewers — was an imposter. However, it was eventually revealed that it was in fact the real Luke Spencer who had suffered a psychotic break (via SoapHub).
Not long after, Laura Spencer reappeared in town requesting that Luke accompany her to Cassadine Island where Frank Smith was holding their son Lucky Spencer (Jonathan Jackson) hostage, according to Soap Opera Digest. In order for the plan to work, Luke and Laura had to pretend to be in love and Tracy was left heartbroken when Luke ran off with his ex-wife. Later, after Lucky has been saved and Jake Spencer (James Nigbor) is discovered alive, Luke tries to reconcile with Tracy but she’s not interested.
