Can the Liars trust Mona Vanderwaal (Janel Parrish)? No, of course not  — but she did the damndest to prove that they can on the Pretty Little Liars Season 4 premiere (Season 4, Episode 1: "'A' Is for A-l-i-v-e"). In fact, she sat down and dutifully answered many of the burning questions that have been eating away at the Liars (and fans!) for ages, and then showed them her lair.

So, what did we learn from Mona? We've collected all of her answers here. Should you believe them? Well, that's up to you.

She didn't get Wilden's car out of the lake. She did put it Hanna's garage, however.

What's Shana and Jenna's connection? "Shana knew Jenna before she came to Rosewood. I think she's in love with her. They're both afraid of Melissa."

How does she knew CeCe? "When CeCe came to Radley, I thought she was Ali. I don't remember what we talked about. It was before they changed my meds."

Who gave Emily that massage? At one point, Emily was given a creepy massage by someone she thought was "A", but we know Mona was busy at the time. Apparently the culprit was Lucas. "He said you were tense."

When did she "recruit" Toby? When he "got that job in Bucks county."

Who pushed Ian off the bell tower? Not Mona. "I wish I knew who did."

She has her own set of keys to Emily's car. This wasn't a question, but something she admitted after explaining she "borrowed" Em's car to go pick up coffee. We're basically going to assume she has copies of everyone's keys from now on.

She was the one dressed up as Caleb on the Halloween train. In case there was any doubt.

Wilden was one of the Queens of of Hearts (yes, there were two). She claimed the second was Melissa, but we didn't see that on video.

What was Mona's most interesting revelation? What else do you want to know? Let us know in the comments below!
