Storylines
1978, 1980–81
Irene Clayton is introduced on-screen in fictional Llanview, Pennsylvania, on the episode first-run May 27, 1978. The former best friend and college roommate of central heroine Victoria Lord, she arrives asking Viki to permanently adopt her 16-year-old daughter, Tina Clayton, as she is ostensibly dying from terminal cancer. Soon on her deathbed, Viki promises Irene to take care ofTina, and Irene apparently succumbs to the illness on-screen in July 1978. Soon later, her legal widower Ted Clayton arrives in Llanview in 1980 hoping to con assumed daughter Tina and her adoptive mother Viki out a portion of the Lord family fortune. When Ted's plans are foiled by Tina, he goes on a killing spree, murdering Vinny Wolek before he-himself is killed by police officer Ed Hall in 1981.
1984–85
After leaving town, Tina returns to Llanview in 1984 with Irene's diary, which reveals that Ted Clayton was not her biological father. In 1985, when Tina learns that Viki's father, Victor Lord, and her mother were married, she freezes the assets of Victor's widow, Dorian Lord, and Dorian's marriage to Victor is declared invalid. Later, Tina discovers a secret room beneath the Lord estate, Llanfair, and finds a letter from Victor meant to be delivered to Viki. In the letter, Victor Lord admits to having an affair with Irene and even marrying her. The letter further reveals that he knew that he was Tina's real father prior to his apparent 1976 death. A stunned Viki initially thinks the revelation and letter to be a farce, suffering a brief bout with her multiple personalities. When she recovers, Viki recalls a repressed memory of Victor and Irene in bed together and welcomes Tina into her family as her sister.
1994–95
In 1994, Dorian Lord is criminally charged with the 1976 murder of then-husband Victor Lord, an assumption many in Llanview held since The Banner founder's apparent demise. After Dorian is convicted and sentenced to death, conman David Vickers arrives in town with another copy of Irene's diary, which reveals a confession from Irene of having smothered Victor to death. David forges the parts of the diary in a scheme to get his hands on the Lord family male inheritance, posing as the secret son of Victor and Irene. Diary entries from Irene reveal she and Victor continued an affair after their divorce, and that she had given birth to his son. David Vickers claims to be that son, seeing a way of getting a piece of Viki's family fortune. In December 1994, Todd Manning finds a letter, following the death of his apparent father, Peter Manning. The letter, written by his then-deceased apparent mother, Barbara "Bitsy" Jones Manning, reveals that Todd is adopted, and Peter to be Irene's cousin. As the son of Victor, Todd is now entitled to $30 million inheritance.
2011
In the summer of 2011 a man with Todd's original face shows up in Llanview, claiming that the man who everyone has believed to be Todd for the past eight years an imposter. After a DNA test is conducted, it is learned that both men or both "Todds" share identical genetic makeup. Attempting to explain how the two men could share the same DNA, Victor and Irene's granddaughter, Starr, believes the two men might be twins. A very-much-alive Irene reappears in August 2011 at Llanfair, eventually admitting to Viki and Lord family relatives that the two men were, in fact, twins, and that the man who claimed to be Todd Manning from 2003 through 2011 was actually born Victor Lord, Jr.. Irene set a bomb on the estate to kill Todd's family unless Todd gives Irene an unknown microchip that she needed. Todd convinces Starr to help him escape and they make it to house in time to warn everyone about Irene's threats. Todd remembers where the microchip Irene is after is hidden and runs off to meet with her. Meanwhile, Bo Buchanan comes to arrest Todd and Starr, Bo discovers the bomb and gets rid of it in time to save himself and the rest of the Lord/Manning clan. After Todd throws the microchip into the river, Irene shoots him and leads him to believe that his family has died in the explosion. On the episode first runOctober 3, Todd shoots and kills Irene. It is revealed when Todd Manning crosses over in-continuity on soap opera General Hospital that after Todd is charged and prosecuted by Llanview District AttorneyNora Buchanan, he is acquitted of his mother's killing because of emotional duress suffered in an episode of post traumatic stress disorder when Irene lied about having killed his relatives.
