The fifth season of Pretty Little Liars is just starting to pick up speed, and in honor of the 100th episode, we want to make absolute sure you're all in. If you spend most of your time theorizing about "A" (because who knows, "A" might still be out there), or just obsessing over Aria Montgomery's best faces, we have a feeling you know how it goes. That's when it hit us: are we too obsessed? Has this gone too far? Take our quiz if you feel like you might might be a Pretty Little Liars fanatic, because the first step is admitting we all have a problem.
