Expect Some Fun Callbacks in the 'Pretty Little Liars' Series Finale

Pretty Little Liars fans will catch some fun Easter eggs and callbacks in tonight’s series finale.

Showrunner Marlene King confirmed some cool cameos and hinted that we’ll likely hear some familiar music too, maybe even dating back to the pilot episode.

“We haven’t seen Melissa (Torrey DeVitto) in so long, I’m really glad we got to bring her back for this closure,” Marlene told EW.com. “All the people who were in the pilot that are coming back, it’s really fun to have them just because it felt so full circle and like having the family all together again.”

“I think as a storyteller I’ve tried to do that a lot in our premieres and finales,” she continued. “We all have always loved doing that on the show. I definitely watched the pilot several times before I wrote the finale and wanted to make it feel as full circle as possible, even down to the music and working with our composer on the score.”

Pretty Little Liars airs TONIGHT, June 27 at 8 p.m. on Freeform.
