For those who like shocks, the Pretty Little Liars Season 3 summer finale certainly delivered.

Although the biggest surprise of the night clearly goes to the betrAyer, Caleb (Tyler Blackburn) getting shot was a pretty devastating moment, too. But who pulled the trigger?

We didn't actually see the moment, and Nate seemed on the verge of dying, so fans are spinning all sorts of theories about what happened. We've even seen speculation that Caleb shot himself as some sort of vast "A" conspiracy!

So, of course, one fan took to Twitter to ask PLL writer Bryan Holdman to clear things up.

Fortunately, Bryan was happy to give a very definitive answer as to who shot Caleb: "Nate, right before he croaked." 

For those who question if that's possible given Nate's state at the time, Byan added, "Take another look— Nate was still moving when Caleb set the gun down."

Our guess is that Nate was actually hoping to hit Emily (Shay Mitchell), and poor Caleb got caught in the crossfire. This is why guns are dangerous, right guys?

Catch the PLL Halloween special on Tuesday, October 23 at 8 p.m. ET/PT on ABC Family.
