Editing Luke and Laura (section)

===Ice Princess saga (1981–1984)===
While Laura attempts to find Scotty, who has fled to Mexico, she continues to pursue Luke and moves into the same apartment building as him. Meanwhile, Luke takes a job with wealthy [[Edward Quartermaine]] (then played by [[David Lewis (American actor)|David Lewis]]) and his niece Alexandria (Renee Anderson), who are searching for the Ice Princess, the world's largest uncut diamond. Also in pursuit of the diamond is Mikkos Cassadine ([[John Colicos]]), a wealthy Greek tycoon bent on world domination. Luke and Laura reconcile and decide to get married when [[Robert Scorpio]] ([[Tristan Rogers]]), an agent for the World Security Bureau (WSB), informs Luke the statue the diamond is hidden in also contains a formula for a dangerous substance called "carbonic snow" that is powerful enough to freeze Port Charles.

Alexandria, working with Mikkos's brothers Victor and Tony ([[Thaao Penghlis]] and Andre Landzaat), acquires the diamond and decides to deliver it aboard ''Titan'', the Cassadines' yacht and brings several Port Charles residents with her. Luke and Robert stow away on the yacht. They are shocked to discover Laura has done so as well. The trio arrive at Mikkos's private island in the Atlantic and discover he is planning on using the Ice Princess to hold the world for ransom, threatening to send the world into a new ice age. He also reveals Port Charles is to be used as an example, and soon the city is plunged into a blizzard, despite it being the middle of the summer. Alexandria and Tony are killed when they try to stop Mikkos. Luke is able to figure out the correct password to turn off Mikkos's machine. After struggling with Luke, Mikkos is killed. Luke, Laura, and Robert are hailed as heroes when they return to Port Charles. As Luke and Laura prepare to marry, [[Lee Baldwin]] ([[Peter Hansen (actor)|Peter Hansen]]) reveals he drunkenly burned Scotty and Laura's divorce papers. Lee attempts to find Scott in Mexico, but when they are unable to, Laura decides to have a [[Mexican divorce]], risky since the divorce would be invalid should Scott ever contest it.

Luke and Laura marry on November 17, 1981, in a lavish ceremony officiated by the mayor of Port Charles, with hundreds of residents from Port Charles and Beecher's Corners in attendance. Bobbie and Laura are able to come to an uneasy truce, since they both love Luke. However, Mikkos' widow [[Helena Cassadine]] (then portrayed by [[Academy Award]] winning actress [[Elizabeth Taylor]]) arrives. She secretly places a curse on the couple during their reception, as she blames the duo for her husband's death. Later, Scott arrives. After catching Laura's bouquet, he declares he is contesting his divorce. As had occurred at Luke's aborted wedding to Jennifer, the men begin to fight. This time, Luke is the victor.

Scott is able to be talked out of contesting his divorce. In 1982, Laura mysteriously disappears off of a pier in Port Charles and is presumed dead. Jackie Templeton ([[Demi Moore]]) reveals her sister Laura Templeton ([[Janine Turner]]) disappeared under similar circumstances. The two friends discover a thief named David Gray was behind the disappearances. While Laura Templeton was not harmed, Gray revealed he had killed Laura Spencer, leading Luke to kill him during a fight. Luke, though still uncertain about his wife's ultimate fate, begins an affair with scam artist [[Holly Sutton]] ([[Emma Samms]]). Their affair is cut short when Luke is presumed dead in an avalanche. Holly falls in love with Robert, despite Luke revealing he is alive. 

In 1983, an increasingly lonely Luke decides to run for mayor of Port Charles, and wins the election. While celebrating his victory, Laura Spencer reveals she is alive and had been kidnapped by the Cassadine family. Mikkos' cousin (later retconned as eldest son) [[Stavros Cassadine]] (then played by John Martinuzzi) had spared her life since he had fallen in love with her. He forced her to marry him, although the marriage was invalid because she was already married to Luke. Stavros came to town to claim his wife but was killed after falling down a flight of stairs after a struggle with Luke. The couple attempted to settle into their roles in politics but found the roles stifling, and decided to leave Port Charles in order to see the world. 

In 1984, Robert helps Luke when he is accused of murder in Mexico, so that Luke would be free to be with Laura. When Luke is finally cleared, he returns to Laura, who announces the joyous news that she is pregnant. The Spencers immediately share their news with their friends. With this revelation, Luke and Laura made what seemingly would be their last appearance on ''General Hospital''. In the following years, passing references to the couple would be made by several characters. 

Later that year, Laura's mother Lesley appears to die in a car accident (later revealed to be arranged by the Cassadine family).
