The more we think about it, the more confident we are that Ezra Fitz (Ian Harding) is going to make a big sacrifice to help the Liars in the Pretty Little Liars Season 4 finale (Season 4, Episode 24, "A Is for Answers."). We're talking about something life-endangering and love-proving. Something that might possibly even redeem him, at least in Aria's eyes.

Why does this theory seem so likely? Here are a few reasons — including spoilers, so watch out! — that we're preparing ourselves to see Ezra make a big move when we tune in tomorrow.

1. Someone gets hurt. We know one thing for sure: one character gets injured, big time, in the finale. It's supposed to be a well liked character, so we're not talking CeCe getting taken down or something like that. Ezra and Ali make the most sense to us, with Ezra taking a slight lead because it would fit so well with a possible redemption arc.

2. He's supposed to still be a good person, apparently. While we're pretty sceptical that Ezra can be brought back from the depths of creepiness that were revealed this season, Ian Harding insists his character really is a good person, and says there is room for redemption because of that. What better way to prove that he really is on the Liars' side than putting himself in danger to save them?

3. There's hope for Ezria. Most importantly, the writers have always insisted that there is hope for Aria and Ezra's relationship. Right now, Aria seems like she'll never forgive Ezra for his numerous betrayals, so it would definitely take something huge to convince her to give him another shot. What's bigger than him almost sacrificing his life?

Of course, none of this is to say we necessarily think this is the most interesting move the writers could make (we'll have to see how it plays out, if we are right) — it just seems to fit.
