The flirty blonde's latest plot has seen her grow close to businessman Carl King (Tom Lister) - and the pair are to embark on a full-blown affair in the next few weeks.
However, speaking to Take 5 magazine, Shaw explained that fans will see Eve feeling guilty over the clandestine relationship because she is fond of Carl's partner Chastity Dingle (Lucy Pargeter).
Shaw commented: "The good thing about this storyline is that the viewers will see a softer side to Eve. She's become close to Chastity and we'll see her struggling with her conscience."
The actress has been part of the Emmerdale cast since the beginning of the year, when she signed up following a number of West End roles.
Reflecting on how she has settled in, Shaw added: "I love being in such a tight little family. Everyone watches out for one another. But I was terrified on my first scene. I had to walk through the village and it was a really emotional moment.
"Luckily, my on-screen gran Shirley Stelfox has been a real mentor. She's stern both on and off camera, but she's been amazing and has given me lots of technical advice."
