When they ask if she wants to complete a rape kit, Abby challenges them on the use of one, noting that rape kits are generally left unattended by police and rape cases rarely end in favor of the victim. They explain that Abby's ultrasound reveals that she has a tear in her diaphragm and needs surgery, but if they sterilize her for surgery, they'd get rid of any evidence that may help her case. She and Jo strike up a strong bond and then Jo and Teddy Altman (Kim Raver) reveal that they know Abby's been assaulted. Abby, who is still disoriented and skittish from her attack, quickly becomes overwhelmed as Jo examines her. She rebuffs his offers to talk and heads to work, which is where she meets Abby (guest star Khalilah Joi), a woman who comes in with injuries after being attacked at a bar. When she returns to Seattle, Jo is visibly unsettled and Alex picks up on it. Despite loving her, Vicki knew she couldn't handle raising the baby who reminded her of how much he hurt her, so she gave Jo up. She explains that she went on a date with a boy who wouldn't take no for an answer and never told anyone about it, because rape "wasn't a thing" back then. It's when Jo asks about her father that Vicki lays out the hard truth she's kept to herself for years: Jo is the product of rape. What is she like? Why did she give her up? And what can Jo learn that doesn't come from "spitting into a cup?" She's also not very happy to see Jo at her front door, though Jo convinces her to meet at a local coffee shop where she prods Vicki for answers. When she meets her birth mother, Vicki, Jo is instantly caught off guard when she realizes that instead of the down-on-her-luck mother she expected, Vicki is well-to-do and lives with her husband and two other children. Inspired by DNA results that led her to the discovery of her mother's identity, Jo heads for Pittsburgh to track down the woman who left her in a fire station all those years ago.
