Here’s what happened in the world of Pretty Little Liars this week.

- This week’s episode was full of sooo many interesting clues. First Jason dropped a hint that Ali might have a secret twin. Then Emily remembered that whoever abducted her had a very distinctive mark on their wrist, the same stamp that Holden has. And that stamp might have some connection to the NAT club.

- Speaking of clues, here are our “A” suspects from this week’s episode. (Holden, we’re on to you!)

- Excuse us if this shows our age, but what the heck are a bunch of underage teens doing at a roving, stamp-accessed party in suburban Pennsylvania?

- Spoiler Alert! We found out the episode title for the Season 3 winter premiere in January and who will be featured in the upcoming Halloween episode.

- Spoiler Alert again! Alison might be alive, at least according to this crazy new sneak peek.

- Do you know the real names of the Pretty Little Liars stars? You’d be surprised at who changed their name, and why!

- Put on your speculation hats, everyone: Marlene revealed a new photo clue for the summer finale. What could it mean?
