What's The Most Shocking TV Betrayal Of All Time?

Bonus points for a dramatic "I TRUSTED YOU!" scene after the main character finds out.

I love a good plot twist on a TV show.

HBO

But I think my favorite sort of plot twist is when a character that seemed trustworthy turns out to be a villain.

The WB

Like when Mona, Hanna's best friend, turned out to be A on Pretty Little Liars.

Freeform

Or when it turned out Michael was a demon and had been working against our faves the whole time on The Good Place.

NBC

Or when it turned out Judy was the one who killed Jen's husband on Dead to Me.

Netflix

Or when Harrison Wells was revealed to actually be Eobard Thawne/The Reverse Flash on The Flash.

The CW
