Shay Davydov is Cosima's ex-girlfriend, whom she met through the Sapphire dating app. Spiritual and easygoing, both of them hook up easily after several dates.


Season 3

In "Scarred by Many Past Frustrations", Shay walks into a local bar that Cosima is waiting for her at. There she introduces herself and asks Cosima if this is her first Sapphire date. Realizing that Cosima is nervous, she explains her first online date. Shay then tells Cosima that she is a prairie girl, hates the winter, has two siblings, her parents are divorced and that Barcelona is her favourite city. The two of them talk about their jobs and what they entail. Shay's practice focus's on one's nutrition, body works and spiritual counselling. She tries to figure out whether people are in balance and helps people get there. They are then seen having photos taken of them from afar by an unknown source. Shay then says that she is able to "see inside your soul".

Later, Shay is seen giving Cosima a massage. Shay asks if she wants to talk about the break up between Cosima and Delphine and then asks if she, Cosima, wants her to go. Shay starts to seduce Cosima, asking her if she wants her to stay but Cosima hesitates on an answer before she says that she doesn't know and Shay says that she'll leave. Right before she leaves, Cosima talks about Delphine and says that she doesn't know what she is doing, but she (Shay) is way more than she expected before they kiss.

Although Cosima keeps seeing Shay, she remains suspicious of Shay. When Cosima discovers a Dyad report on Shay that reveals she is ex-military, Cosima turns cold on her.
