Ever find yourself utterly crushed when a beloved TV character suddenly does a full 180, leaving you wondering if the writers accidentally switched personalities with, say, Mercury in retrograde? Yeah, me too. There’s something oddly cosmic about those arcs that dive off a cliff faster than a Scorpio scorned. Take Criston Cole from House of the Dragon—one minute you’re rooting for the guy, and the next, you’re like, “What just happened?” It’s like the stars aligned to mess with our TV hearts, serving us unexpected twists that either deserved a standing ovation or a collective eye-roll. So buckle up, because we’re diving into 15 character arcs that nosedived so hard, they made me question if the writers checked their horoscopes before scripting. Ready to witness some dramatic plummets and maybe catch a bit of that astrological chaos at play? LEARN MORE

15 Worst TV Show Character Arcs That Went Downhill So Fast

We are all familiar with TV series that we adore and cherish, that gradually lost their allure thanks to a single character whose arc development ruined the plot. I have felt that way with Criston Cole from House Of The Dragons, and might I say—he had it coming.

Some characters soared, some fell because they had it coming, and some crashed in ways no one could’ve predicted. Here are 15 TV characters whose downfall stunned us all:

2.

Jaime Lannister, Game Of Thrones

7.

Dexter, Dexter

8.

Hannah Baker, 13 Reasons Why

9.

Jenny Humphrey, Gossip Girl

10.

Andy Bernard, The Office

11.

Criston Cole, The House Of The Dragons

12.

Eric Foreman, That ’70s Show

13.

Gregory House, House

14.

Toby Cavanaugh, Pretty Little Liars

15.

Alex Karev, Grey’s Anatomy

Nothing ticks me off more than a poorly written character or a plummet from good to evil. For a show to be fulfilling, the characters always have to reach their full potential, and that’s the way viewers like myself can be satisfied. While the above characters are already done for, I will just have to revisit Peaky Blinders and other series to have the joy of a flawless character development conclusion.
