Bet you didn't see that one coming! Did you?

If you have not seen the second season finale of Scream, then you might want to stop reading now.

After the thrilling second season of Scream aired its finale on Tuesday night, the killer was revealed to be none other than Kieran.

The series began its second season with Emma returning home from a PTSD camp to get her life back to normal with friends (and her unknowing psychotic boyfriend) by her side after her half-sister Piper killed a number of Emma's friends. But it turned out that Piper had an accomplice as more people got killed.

With suspects all over the place, Emma and Audrey were accused of murdering Brooke's father by the end of the season, which led to the question on who was really guilty-- shockingly enough, Kieran was the psycho in charge of the murders. And instead of the killer dying like in the first season (as well as in the Scream movies), Kieran was taken to a prison where something pretty crazy happened.

The show's most mysterious character Brandon James may actually be alive since not only did his response from a letter involve a knife...but Kieran received a mysterious phone call from someone who claims to be the owner of the mask.

Enstarz spoke to Amadeus Serafini (Kieran) on that shocking finale, his previous theories on who the killer could've been and what could happen if the show gets renewed for a third season.

Enstarz: What was everyone's reaction when they found out you were the killer?
Amadeus Serafini: I think it was a shock. I think there might've been some expectation on some people's parts in the cast. We were trying to figure it out the whole way along in the first season and next season, and different people get implicated all the time and of course every table reading would implicate different characters and we're always quick to try to point the fingers to each other. This time it was a shocker, but it was real and made sense with Piper's backstory and all of that.

Did you have suspicions on other characters who could've been the killer?
I wanted to be the killer early on in the season, but I also wanted to be the killer in the first season and I was not. So I had no expectations. In terms of my own suspicions, I always thought Audrey was suspicious, I always thought Noah was suspicious, but they were always in the right place at the right time. And then, of course, we have Stavo and Eli and Zoe, and I think there was a creepiness factor there, but also there were potentially two suspects so I still wasn't sure at that point.

How did you feel about this ending versus last season since the killer doesn't die this time?
Well, it's good for me [laughs]. In the movies, the killer always dies. So I'm not dead and I don't know what this is going to entail should there be a Season 3 or not. I'm in prison and probably a maximum security prison with the number of people I slaughtered. So I don't know what's gonna happen or where it could go.

Do you think it's possible that Kieran could've done more killings in the first season that weren't from Piper?
It's possible. Likely not so much since Kieran's always in the right place at the right time as well in the first season. But he is implicated, you're right. He's a prime suspect in that first season.

Kieran obviously has major daddy issues, but do you think there's more that set him off?
I think so. And that's really the only way I was able to play it for myself occupying this character in that last episode. But there's so much that needs to be seen. Not a lot was exclusively scripted so it's left up to the audience to wonder and, of course, left up to Season 3-- if there is one-- to fill in those blanks.

Do you have any theories on what could happen if the show gets a renewal?
Our showrunners have done a tremendous job withholding information, and it works. Kieran's in a maximum security, I don't know what he's gonna do. He might have to join a prison gang?

Where do you think the other characters are from here in their relationships with each other?
Oh man, can you imagine the trust issues? Kieran was dragging them along for two years. I don't think Emma's gonna recover. But they still have that pipe root and they're still together.

In the finale, there's the scene where Audrey and Emma are attacked by the killer in a police car that crashes. The movie Scream 2 has a similar scene. Was that supposed to be a reference to the movies?
Absolutely, it was a reference. I think the writers and the showrunners have really incorporated a lot of that throughout the season and you'll pick up pieces of it here and there. And some of the references are taken from characters and placed on other characters. You have Stavo who climbs into Brooke's bedroom and that's a Billy Loomis [reference]. But he's not the Billy Loomis type necessarily, Kieran is. But they mixed up all these elements and it peaks the audience's interest especially those who have seen the movies and are drawing on those clues.

Anything else you'd like to add for readers to know?
Stay tuned! There's gonna be exciting stuff to come hopefully! I don't know if there's a Season 3 or not, but hopefully!
