After Shelia consumed the infected clams and became undead, Abby attempted to become involved in her parents' dangerous activities, but Joel and Sheila tried their absolute best to protect Abby from their new lifestyle- wanting her to have an ordinary life. This would ultimately fail, as the truth was unavoidable.
Abby is a strong-headed and sardonic girl. She has an assertive and forward personality, and has shown she is not adverse to combat. Throughout the series, she handled her mother's mutation and cannibalism with tact, going out of her way to hide the fact that she knew of her parents' murders, though is not without her own trauma.
Abby has proven to stand up for those who cannot stand up for themselves, notably with Eric Bemis and her attempts to get him to retaliate against his step-father. By taking on the role of heir for her dad, she also shows great selflessness and courage and even willingness to handle hard situations. She is a major character in the series.
Abby is considered shy and socially awkward, and she struggles to make friends. Her next door neighbor, Eric Bemis, has become her closest friend and love interest. She clearly displays affection for Eric, but struggles to accept that she feels that way and often feels uncomfortable with any rumor that circulates that would indicate that way. In the Season 2 finale, she initiates a kiss with Eric due to the fact she thinks her family is leaving. After finding out her family is safe, she brushes it off, much to Eric's dismay. The two also blow up a fracking site together, causing them to grow closer as they try to cover up their act from the FBI.
However, in the season 3 finale "The Cult of Sheila," Abby comes to terms with her feelings for Eric and sneaks into his room one night. When Eric asks what's happening, she replies "I don't know. I thought maybe we could try and find out."
