No matter how much we pay attention, good television shows always manage to hit us with the unexpected.
Whether a character is being betrayed by their friend, family, or ally, betrayals always manage to shock viewers and take the storyline in a new and surprising direction.
Below is a slideshow featuring 19 betrayals that no one saw coming and still have us shaken to our core. Obviously, because of the nature of this list, a potential spoiler alert is in order.

While the audience knew Wells was up to no good, Team Flash remained blissfully unaware of the traitor in their midst. The betrayal of someone who was so important to all of them left everyone in shock for quite some time.

After being tortured by a mysterious cyber bully for seasons, the show revealed that Hanna's best friend Mona had been the one pulling the strings. No one, including the liars, saw that twist coming.
John poisons Steve - Days of Our Lives
Considering just how close John and Steve were it feels safe to say that John poisoning his partner was an unexpected turn of events.
Ward is a HYDRA Agent - Agents of S.H.I.E.L.D.
Grant Ward definitely was an agent...he just wasn't a S.H.I.E.L.D. one. His friends were both disheartened and shocked to discover that Ward had actually been working for HYDRA the entire time. The reveal certainly spiced up his character for viewers who found Ward to be too bland.
Willa tries to free the revenants - Wynonna Earp
When Willa miraculously came back from the dead it seemed like the Earps were finally going to get to be a family again. But Willa wasn't the girl she used to be, and she ends up pulling a gun on Wynonna and Waverly in an attempt to be with Bobo and free the revenants.
Sebastian is actually Jonathan Morgenstern - Shadowhunters
Shadowhunters really hit the nail on the head with the dramatic irony. While the viewers were aware for quite some time that Sebastian wasn't who he claimed to be, Clary and her friends had no idea. Each episode made watching our beloved characters be duped by him increasingly frustrating.
