Pretty Little Liars has never been the most realistic show around. After all, Rosewood is a town where teens run around trying to solve a murder mystery, a girl faked her death, and just about every single adult is corrupt. That's part of the fun of the show.

Even with that in mind, there are occasionally moments that make us stop and say, "Really?" Sometimes it's something that doesn't make sense from the writers, and (more often) it's just that we want to reach through our TVs and smack the characters upside the head for making bad choices.

Here are our picks for the biggest logic fails and WTF moments from Season 4, Episode 20 ("Free Fall").

Aria and Ezra didn't go after the papers. You drop a bunch of super revealing pages, and you don't go to retrieve them? We get that Aria probably just wanted to leave, ASAP, after Ezra's big reveal, but you'd think he'd go reclaim his work. Unless he really is "A" after all, and that was him we saw at the end of the episode (but that appears to not be the case).

Spencer's call to the doc. We know Spencer isn't thinking clearly right now, but we have a hard time believing such a smart girl would be dumb enough to leave a message at her doctor's office pretending to be her mom. Of coursethe doc called her mom back. Spencer should have just hung up.

Ezra's whole story. This deserves an article of its own, but we just don't buy that Ezra's story explains all of his behavior. Even the most obsessed reporters don't normally stalk teenaged girls. And what is up with this connection to Mona? Why would she be helping him with his book? Maybe this will all be explained eventually, but for now we're left scratching our heads.

 Did you pick up on any logic fails this week? Let us know in the comments below!
