Kelly Monaco joined the cast of Port
                           Charles as Livvie Locke, daughter of Dr. Kevin Collins, unknown to both of them.  She ended up in Port Charles because
                           her mother, Rachel was there.
                            
                              Rachel did not want her there because
                           she didn't want Livvie to find out that Kevin was her father or vise versa.  Livvie befriended Lucy and went by the name
                           of Charlie McMillian and moved in with Lucy.  She had terrible nightmares and actually became Kevin's patient. 
                           
                            
                              Rachel blamed Kevin for her sister,
                           Grace's death and wants revenge against him.  Livvie
                           found out a bunch of lies about her life and things that were told to her so when Rachel tried to get Kevin in trouble Livvie
                           came in to save Kevin, who he thought was Charlie McMillian too and Livvie blew everyone away with the news that she
                           was Rachel's daughter.  
                            
                              Lucy of course starting thinking that
                           Livvie might be Kevin's daughter so she had a DNA test done without anyone's knowledge and come to find out she was Kevin's
                           daughter.  
                            
                              Grace had Livvie by Kevin and never told
                           him and didn't want Livvie so Rachel who is really her Aunt, kept her and raised her as her own and then Grace died in a car
                           accident that was her fault but everyone blamed Kevin.  Livvie finds all of this out and is really upset because she
                           thinks her whole life was one big lie.  
                            
                              Rachel hates Kevin so much that she actually
                           told him that Livvie was Ryan's.  Ryan now deceased is Kevin's twin brother who was a serial killer.  Kevin found
                           out that it wasn't true and that Livvie was really his and he wanted to get to know her but Livvie was just confused and upset
                           and decided to stay with Lucy.  
                            
                              Livvie then met Jack at the river where
                           he made her fear of water go away.  She really liked Jack and they hooked up but then broke up because she thought he
                           was usuing her to get back at Chris.  They finally hook back up and have a wonderful relationship.  
                            
                              Livvie and Jack became best friends with
                           Jamal Woods and Alison Barrington and they all ran the bike shop together.  Jack and Livvie went camping and something
                           happened to Jack while he was in the woods and he started acting strange and can't figure out what's wrong.  
                            
                              Then enters this stranger into town who
                           intrigues Livvie.  He shows up where she is and she tells him to leave her alone but she is drawn to him for some reason. 
                           Zach, a bad guy that Jamal once knew shows up and blackmails Jamal into racing his bike.  
                            
                              On the last race Zach was going to have
                           Jamal take drugs where he was racing and Alison didn't want him to race because she knew that Zach was going to do something
                           bad and was scared so she threw his keys into the bushes.  Zach held Livvie hostage and made Jack race in Jamal's place. 
                           
                            
                              They run Jack off the road and he ends
                           up in an accident and dies.  Livvie is beside herself because she lost the only man she ever loved.  So Livvie,
                           Jamal, and Alison build a wooden coffin and bury Jack in the woods because they didn't want Jamal to take the blame and go
                           to jail.  
                            
                              They are scared when they get home and
                           tell everyone that Jack stole money and ran off.  Livvie swears she will get revenge on Zach and goes and finds him and
                           threatens him with a knife but he overpowers her and throws her on the ground.  
                            
                              The stranger she met who turned out to
                           be Caleb Morley, the vampire saved her from Zach.  Livvie then left and went to the river because she was so upset over
                           Jack and then all of a sudden Jack walks up and she can't believe it and then Jamal and Alison walks up and they can't believe
                           it and they tell him what happened because he can't remember.  
                            
                              Come to find out he had gotten
                           bitten by Caleb in the woods and broke out of the coffin with his superhuman powers.  Caleb continues to pursue Olivia
                           because he wants her for his own.  He  manipulates
                           Livvie and she falls under his spell and in love with him.  
                            
                              Her friends and family try to warn
                           her and stop her and she tries to stay away from Caleb but what they have together is too strong to resist.  She turns
                           her back on all of her friends and family to be with Caleb, but in the end it is she who kills Caleb.  
                            
                              Livvie drives a stake through Caleb's
                           heart and  starts wreaking havoc on everyone in Port Charles. She ends up losing all of her friends. She lost Jack
                           and blames her best friend, Alison for everything that happens to her.  Caleb enters back into Port Charles and so does
                           a mysterious girl named Tess who looks exactly like Livvie. Tess also played by Kelly Monaco is the result of Caleb. 
                           
                            
                              Caleb pulled all of the good out of Livvie's body and
                           that's how Tess came to be. Tess has now gotten Livvie inside of her body because she doesn't want Caleb to
                           hurt Livvie.   Finally Livvie comes out and Tess is gone for good. 
                            
                              Livvie and Caleb are together and he has turned her,
                           will they live together happily ever after? Or will all of Livvie's schemes tear them apart?  Maybe their love is strong
                           enough to keep them together, no matter what.
