However, after Larry Bryggman returned to the show on August 27, 2010, Bob Hughes mentioned that Dixon had been at Johns Hopkins.

Protégé of the late Michael Shea, Dixon was a constant thorn in the side of many Oakdale residents.

The son of a working-class family, John was jealous of the affluent Stewarts and Hughes and felt that their lives were served to them on a silver platter.

His opportunity came when he discovered that Kim was pregnant with her brother-in-law, John's professional rival, Bob Hughes's, baby.

Desperate to keep his wife, John blackmailed her into staying married to him by threatening to tell Kim's sister the truth about her pregnancy.

John had an obsessive need to stay married to Kim and conspired with Dan's ex-wife, Susan, to keep the two apart.

By the time Kim's memory returned, she was pregnant with John's baby and Dan had left for South America.

John lied and told everyone that Dan tried to kill him and married Pat Holland so that she wouldn't be forced to testify against him.

Dee was young and emotionally fragile following the death of her lover Ian McFarland, who died as they were making love.

John alienated Dee from her father, David Stewart, and made her believe that her sister was pregnant with Brad’s baby.

Soon, Armond Elliot, a movie producer friend of Ariel's offered to buy the rights to John's book.

After Ariel made John promise her a big wedding, a house and travel, she agreed to be his wife.

First, she went on a shopping spree, then purchased twenty acres of land and made plans to build tennis courts and a pool.

Despite his anger, John was still attracted to Ariel, and after making love, she showed him the blueprints and told him the house would cost around a million dollars—she'd already made the down payment.

John cut Ariel out of his will and insurance policies and then he gave Margo sealed envelopes containing copies of James's birth certificates and addressed them to Gunnar St. Clair, Barbara and the New York Times—to be delivered in the event of his death.

A couple of days later, Dee confided in Brian McColl and it was apparent that she was emotional over John's death.

Under the assumed name "Robert Allen," Richard Fairchild III met John on a flight from Detroit.

All the doctors were occupied with car-crash victims, and an inexperienced resident asked John to help with Bob.

When Karen got wind of John's involvement with the insane Richard Fairchild she refused to speak to or sleep with him for several weeks.

Finally, Lucinda started goading Karen that she wasn't good enough wife for a doctor with the capabilities of John Dixon.

When he talked to Rick Ryan he learned the reason: the child (Sabrina Fullerton) didn't die in the train wreck after all.

Realizing that Lansing was trying to murder Sabrina, a regretful John went to the police and finally told them of the deception.

Thankfully, though Lansing was arrested, John was cleared of any wrongdoing and Lucinda saved him from being booted out of Memorial.

Unfortunately, Duke's wild ways clashed with Lucinda's sophisticated style and she made plans to get him out of town.

When Lisa's husband died for unexplained reasons, while being treated by Dr. Dixon, she blamed him and initiated a malpractice suit.

John was found guilty until evidence surfaced that revealed that Lisa's husband had, in fact, been murdered.

Unfortunately, Barbara was injured in a bombing and John authorized the early birth of their son in order to save her life.

John decided that Denise wasn't the appropriate person to raise his granddaughter and went to a lawyer to find out about his grandparental rights.

At the same time, Lucinda had no luck repairing her newest rift with Lily and agreed to John’s invitation to accompany him to Amsterdam.

A month later, they returned to Oakdale in love and John accepted an offer as interim Chief of Staff when Bob retired from Memorial.
