|“||I won’t let you turn me into the woman who says "pick me, not her".||”|
— Yvonne to Toby in "Hush, Hush, Sweet Liars"
Yvonne is a bright and generous person, very well spoken with a keen insight into politics. She is a fan of retro television.
Yvonne makes her debut in this episode when talking to Caleb who stops by the site where Toby is building a home. Later on while in town with Toby, she meets Spencer officially for the first time. It seems she also received a campaign packet on Spencer and know many things about her beyond simply being Toby's ex-girlfriend. She later attends a joint event with Spencer focusing on encouraging millennials to get into the democratic process by voting.
Yvonne shows up at a lunch with Spencer, where she was supposed to have a meeting with Gil. However, she doesn't know that Uber A most likely set her up to make her think that Spencer invited her to lunch, during her meeting with Gil. While they are eating inside, Spencer and Yvonne were talking about politics, since Spencer was new at it, and Yvonne knew all about it. She gives her good remarks too, like there's not expectation of privacy, you're always being watched, and you can't trust everyone with everything. After they are done, Yvonne accidentally forgets her phone. Later on, Spencer realizes it and goes to the lost and found to pick it up, only for it to be taken by Mona.
Yvonne is helping set up for the election, talking with Toby. Toby tells her that he won't be able to make it to the party tomorrow, because he's helping out Spencer, much to her dismay. Toby tells her later that what he has to do is too complicated to explain. When she gets up, she tells him that she doesn't want to be the woman who says 'pick me, not her'. Yvonne then gets a call from Toby, and she declines. She stays to watch the campaign, but we don't see her reaction to when her mother lost.
Spencer comes to see Toby to give him Mary Drake's file. She sees Yvonne instead, who makes her understand that she has created problems in her relationship. Spencer apologizes, then Yvonne announces that they are hosting the family that same night to celebrate her engagement. Spencer notices the ring on her finger before congratulating her. In shock, she leaves, deciding not to involve Toby in this story. During the family dinner, Emily arrives to ask Toby for help and after their conversation he tells Yvonne that something came up with work, she asks if it has something to do with his conversation with Emily, but he denies it.
Yvonne is victim of an assault in the trailer next to the house. At the hospital, Spencer comes to see Yvonne and Yvonne tells her that she is fine. Toby then says that the only thing that was stolen from the trailer is Mary Drake's file. Toby announces to Spencer that he and Yvonne are leaving Rosewood and settling in Maine.
She and Toby decide to move out of Rosewood but are in an accident before they get far.
After hitting a deer, she and Toby are sent to the hospital. Yvonne is placed in a medically induced coma due to the severity of her injuries.
She wakes from her coma but is still very weak. She accepts Toby's idea that they marry that very day despite her being in the hospital bed. As Toby celebrates, they discuss where they want to go for their honeymoon. She tells Toby that she is happy before she breathes her last breath, dropping her flowers in the process and leaving Toby devastated.
