10 Most Pitiful TV Plot Twists Ever Created

4. A - Pretty Little Liars

Who was A? The biggest question of all. Everybody had their own theories, with most of them a million times better than the actual A who was finally revealed to be... Alex Drake!

Sorry, who?

Yes, A actually stood for Alex Drake, a little known character that actually didn't really have anything to do with the series at all. In fact, her existence was unknown until the actual final episode.

Seriously, that's the plot twist, a character that didn't even exist.
