Check out these sneak peek clips of the latest episode of “Pretty Little Liars,” titled “Mona-Mania.” The girls sneak down into the school’s basement again to do some more investigating in re: Creepy Harold, the new janitor who apparently has Ali’s journal — only to be surprised by “A”? Yikes. Who else jumped out of their skin?
And apparently Creepy Harold has gone AWOL.

Below, the Liars encounter Mona at the coffee shop. She claims Creepy Harold is stalking her because she used to be friendly towards him at the motel. She also claims he’s the one who set the fire at the 10K. Hmmm.

Raise your hand if you think that’s actually true.

And Paige (Lindsey Shaw) is back! But she’s not acting super friendly towards Emily. We get that she’s freaked out, but wouldn’t Emily be a comfort to her? We’re glad she agrees to go to the swim team party, though we doubt this will end well for them in terms of their parental crackdown.

“Pretty Little Liars” airs Tuesday nights at 8 p.m. ET/PT on ABC Family. Check all the great pictures of upcoming episodes in our photo gallery.
