Pretty Little Liars is a show where events from the past still have a profound effect on the present, and we love finding out tidbits about what went down before we tuned into the story. According to Troian Bellisario, we might have a very interesting flashback headed our way in the second half of Season 4, which got us thinking about what flashback moments we're the most desperate to see.

Read on for our picks of the top four flashbacks we hope make it into the show one day, and then sound off with your own thoughts in the comments below!

The night Ali disappeared — from her point of view. Everyone has a side to the story about the night Ali went missing, but one day we want to hear about what went down straight from the Queen B's mouth.

Some Ezra explanation.  Ezra is on the "A" team? Maybe? We need answers about what he was doing in the "A" liar, and flashbacks would help. Fortunately, it sounds like this wish will be granted. Way to go, show.

The beginning of the Liars' friendship with Ali. This is more emotional than plotty, but we'd really love to see more about the formation of the group. How did Ali choose each of Liars? When did they come together as four friends following their leader's every command? There's a lot of juicy stuff to dig into here, and if Ali really is alive we're thinking the early moments of their friendships would create a very interesting contrast to the present of the show.

Ali's visit to Jenna. We've heard about Ali's visit to Jenna in the hospital after, you know, blinding her, but we've never been shown what went down between two of the show's most fascinating, powerful, and frightening characters. We have a feeling this could be a brilliant scene.
