One of the main themes of The Passage, both the TV series and the book trilogy, could be summed up in the title of S1 Ep8 of the series: You Are Not That Girl Anymore. The major female characters of The Passage have all grown this season and had an impact on the main arc of the story.
The future relies on Amy Bellafonte and how she weathers the virus and her relationship with the other virals. It’s Dr Nichole Sykes’ commitment to Jonas Lear’s vision that made Project NOAH what it is, and she is still an important part of the evolving nature of the virus and virals. Dr Lila Wolgast has provided emotional, medical and logistical support for Brad, Amy, Richards, Sykes and Lacey at key moments. Shauna Babcock is Fanning’s second in command. Lacey Antoine rescued Brad and Amy and gave them a hideout from Richards’ pursuit. Elizabeth Lear was the catalyst for the entire endeavor. She was both Jonas’ excuse for pursuing the Bolivian rumors until the end of the world and the voice of reason in his head telling him he was going too far.
Though there are a few female inmates who have become virals, Shauna Babcock is the only one we’ve seen communicate with humans and whose backstory we’ve been given in detail. Shauna has lived a complicated life, and has created a complicated web of relationships within Project NOAH. Manipulation is her specialty, making it difficult to tell when she’s being sincere and when she’s using someone.
In the story she told Clark, she’s a victim with a tragic backstory who finally snapped. Shauna was regularly raped by her stepfather from the ages of 8-16, until she was old enough to stand up to him and make him stop.
