In an interview with Entertainment Weekly, the girls and show runner I. Marlene King revealed that there was one particular line that was impossible for them to get out without tears.
"Was it the very first sentence that someone had to say something and we all just started crying?" Ashley Benson asked the others.
"We couldn't even do it. We almost weren't able to even start the table read because it was just so heavy."
Sahsa Pieterse cleared it up, saying it was her line: "I feel like this is the end of something."
AHH.
"I couldn't talk," Sasha continued. "Marlene was like, 'Okay, that was great, but just a little less crying.'"
An even sadder line is in the finale, where Spencer quotes a Winnie the Pooh line, "How lucky am I to have something that makes saying goodbye so hard?"
Oh boy, BRB while we go buy 3,000 boxes of tissues.
