What was your reaction to finding out the news that Mona Vanderwaal would die?Janel Parrish: [Creator] Marlene King had been planning it for a year! She did a good job hiding it. I learned right before the table read for the episode two months ago. It's really fine. At first, I was definitely nervous, but she told me not to worry. I'll still have a job. I'm still on the show. I will be flashback girl. Fans will really like it. They'll get a little more insight into Mona's backstory. She's always been mysterious.

The way Mona's house was found [after her death], it looks like she put up a fight.She definitely put up a fight. You'll see more of that in coming episodes. She wouldn't go out without a crazy fight!

If Mona had survived, what do you think Mona was planning?To nail Alison's [who the girls suspect is the new A] ass!

What was your favorite Mona moment?I really enjoyed seeing her that first day in a hoodie as A! It was a powerful moment for Mona and the show.

Will we see Mona in the Christmas episode? Yes! She will be the ghost of Christmas past, present and future! And she'll look fantastic in her costumes.

How is her boyfriend Mike going to react to Mona's death?That was such a sweet relationship. He's going to be devastated.

What do you think about the fan reaction to Mona's death? I'm so happy they are sad! She was so loved. RIP Mona has been trending on Twitter! It's so great people are talking about it.

So it's good to know Mona is not history.I'm not going anywhere! I'll just be here in a different way.

Season 5 of Pretty Little Liars will return on ABC Family in early 2015.
