Fallon is the epitome of the spoiled little
rich girl. The second child of Blake and Alexis's children,
Fallon is willful, impulsive and fiercely protective of
Blake. She is without a doubt "Daddy's little girl." Fallon
hated Krystle when she married Blake. As part of a deal to
bail Blake out of financial trouble, Fallon married Cecil
Colby's nephew Jeff. Fallon was also having an affair with
her father's chauffeur Michael Culhane at the time. The
affair came to an end when Blake found out about it and fired
Michael.
The hatred Fallon felt for Krystle grew when
she found out that Krystle was pregnant. Feeling threatened,
Fallon seduced Jeff and became pregnant as well, but after
Krystle's miscarriage, Fallon wanted an abortion but failed to
go through with it. With her sham marriage practically over,
Fallon became involved with psychiatrist Nicholas Toscanni.
Unfortunately she didn't realize that he was using her to get
back at her father.
Blake Jeffrey Carrington Colby was born by
cesarean section following a car accident in which Alexis
confessed to Fallon that Blake may not be her father. Fallon
lost control of her car when Alexis said her father may be
Cecil Colby. She went into a severe depression and remained
in it until blood tests proved that she is indeed Blake's
daughter. Jeff and Fallon's marriage was strained even more
when their son was put through heart surgery at a few days
old. Nick soon realized that Fallon was going back to Jeff
and took further steps to hurt the Carrington family by
arranging for the baby to be kidnapped.
During the search for her baby, Fallon and the
rest of the world discovered the secret of Adam's kidnapping.
After the safe return of the baby, Fallon took over one of
Blake's properties (La Mirada Hotel) and transformed it into
an extravagant resort and changed the name to La Mirage.
After nearly being seduced by Adam (not knowing they were
related), Fallon unsuccessfully tried to discredit him.
With her divorce from Jeff final, Fallon moved
on to her next two conquests. The first was tennis pro Mark
Jennings. Mark was Krystle's ex-husband that had been tracked
down and lured to Denver by Alexis. Alexis and Fallon had
intended for Mark to break up Blake and Krystle but instead he
fell for Fallon. Alexis didn't like what she was seeing and
broke them up.
A short time later, Fallon met and fell madly
in love with playboy Peter DeVilbis. Despite everyone's
warnings, Fallon planned to marry Peter but he was only after
her father's money. When she realized he had used her, she
ran from the hotel and was struck by a car. The trauma of the
situation left her temporarily paralyzed and caused her to
have tremendously painful headaches. While having Jeff caring
for her, Fallon realized just how much she truly loved Jeff.
On Little Blake's second birthday, Jeff proposed and Fallon
happily accepted.
On their second wedding night, Fallon had yet
another massive headache. This time it was so horrible that
she ran out of the house and drove away in the pouring rain.
She was in a serious accident and several weeks later was said
to have died in a plane crash with Peter DeVilbis. As her
family mourned, Fallon was actually in Los Angeles, California
suffering from amnesia.
She was unknowingly drawn to Miles Colby (not
realizing who she is) and joins him on a trip to Colorado to
attend a party at the Carrington mansion. When she arrives at
the house, she is unable to go inside and she and Miles drive
away without having made an appearance. Jeff is looking out
the window when Miles pulls up and sees Fallon with him. Jeff
moves to Los Angeles and arrives shortly before Miles comes
home with his new wife "Randall." Jeff makes her realize that
she's actually his fiancé and the mother of their child.
Fallon regains her memory and returns to Jeff,
leaving Miles hurt and angry. Her marriage to Miles is
annulled and she decides to marry Jeff again. Miles rapes
Fallon and she becomes pregnant, causing her to not know if
the child belongs to Miles or Jeff. Still living in Los
Angeles at the Colby mansion, Fallon falls down a staircase
and goes into premature labor. She delivers daughter Lauren
Constance Colby and is relieved to discover that Jeff is her
daughter's father.
On an unusually warm night, Fallon is stunned
to be trapped in the desert and sees a very strange light.
She walks slowly towards a spacecraft and boards the craft.
Several hours later, she is found by the side of the road.
Desperate to regain her senses, Fallon begs Jeff to take her
back to Denver.
Once there, Fallon sends for the children and
the Colby family moves back into the Carrington mansion. She
tells Jeff of her experience and he thinks she's lost her
mind. They continue to have problems and divorce again. She
begins dating John Zorelli, a police detective investigating
the death of Roger Grimes. It is later discovered that Fallon
had killed Grimes as a child when she saw him beating Alexis.
Fallon eventually moved back to California where she shared a
home with her children and Krystina while Blake was
incarcerated and Krystle supposedly comatose.
