Alison Hendrix is a clone of Canadian origin on Orphan Black. Alison had already been in contact with Beth Childs when she was approached by Sarah Manning whilst she was under the guise of Beth following Katja Obinger’s death. Alison and Cosima Niehaus explain Sarah’s existence as a clone to her, ending with Sarah joining their pursuit of answers regarding their origins. As time goes by, paranoia sets in on Alison and she begins acting outside of her routine and going behind the backs of her husband, Donnie Hendrix, and her best friend, Aynsley Norris. Alison’s life begins to fall apart, eventually leading her to signing a document created by Dr. Aldous Leekie. Without knowing it, Alison signed away her freedom in exchange for a skewed version of normality that Leekie had promised her.
Not much is known yet about Alison, except that she is married to her high school sweetheart Donnie, and has a typical marriage, with two adopted kids. When Katja Obinger came to Beth, Beth was able to track down Alison and Cosima, and the trio soon found out about their nature as clones. For a long time, it was just the three of them who looked out for each other, while they asked Katja to give them data on the Europeans.
Wanting to protect her family, Alison was taught by Beth how to shoot a gun and keeps a Glock of her own. During this time, Beth was able to contribute with access to records only a cop can access, Cosima with her intellect, and Alison found herself useful by contributing largely to their substantial sum, which Beth used to buy information they couldn’t get officially.
