Significant details about Ava's past are currently unknown.
On April 13, Ava and Lily meet face to face for the first time at the Pine Valley Inn, seeing for themselves that they truly are identical in appearance. Adam Chandler pays Ava to break up Sean Montgomery and Colby Chandler's romance. Ava tells Colby that her father paid her to plant drugs on Sean. This confession results with Colby moving out of the Chandler Mansion. Later, Ava sleeps with Jonathan Lavery, but she thinks that Jonathan only slept with her because she looks like Lily and because Jonathan cannot sleep with Lily. Ava gets a job at Fusion Cosmetics as a model, but after talking with Lily, she dyes her hair brown and she gets fired because of it. But she is re-hired by Babe Carey while Kendall Hart Slater is in the hospital, and returns to her previous hair color. After making love with Jonathan on the beach, she begins to feel sick. Babe asks her if she could be pregnant and Ava says it is probably just a bug. Ava decides that she has to buy a pregnancy test, but she ends up not taking it. As she leaves the Fusion office, she is in pain, and when she exits the elevator, she grabs a hold of J.R. Chandler and begs him for help and she says that if he leaves, she will tell the world that the baby is his. He brings her to the hospital and instead of being pregnant, it turns out she has appendicitis. She refuses to have surgery and Lily tries to convince her to have it. Ava tells Lily about a painful memory about her hitting her head on a table corner and her mom just leaving her at the hospital and her being afraid of dying with only strangers. Lily promises not to leave her and touches Ava's hand. Ava hesitantly accepts the surgery and makes a full recovery.
Lily objects to Ava's relationship with her cousin Sean when they live in Jack's house. She's uncomfortable with touching and sex. She is unhappy to discover Ava's relationship with her ex-husband Jonathan while they are living at Wildwind. She eventually accepts their union because she wants her half-sister to be happy. Ava and Jonathan become engaged after she talks with Lily about it (and freaks out over a wedding dress at Fusion), and even gets a tattoo accepting Jonathan's proposal. Lily helps plan the wedding because she's so good at numbers. But on January 16 2008, Ava tells Amanda Dillon at Fusion that they have broken up. It might have to do with Ava kissing J.R. when he was trying to get her to be the model for his online beauty network.
ABC announced that Ava's appearance on February 19 at the yacht club would be her last. Her character has been dropped of the canvas, and might possibly never be seen again.
