Let's be honest: One of the best parts of teen dramas is watching the characters be completely awful to each other.
Sometimes, though, these betrayals go a little too far. I've always wondered how these characters forgive each other so easily!
Like on 90210, when Adrianna swapped Silver's meds out with placebos as revenge for hooking up with Navid and Silver almost died.
Or on Pretty Little Liars, when Mona literally tortured the Liars for years, all while pretending to be Hanna's friend.
And let's not forget Chuck trading Blair, the supposed love of his life, for a HOTEL on Gossip Girl!
