On the most recent episode of Pretty Little Liars (Season 4, Episode 6: "Under the Gun"), Hanna was on home arrest after being caught trying to bury the gun she found in her mom's closet. It turns out the state police were none too pleased with her antics — and they know she was trying to protect her mom. 

However, the episode's biggest surprise came when Spencer and Toby ventured to Ravenswood, the creepiest town ever, in search of Mrs. Grunwald. Who is Mrs. Grunwald? And what does she have to do with Ali? If only we knew! Sadly, the search for Mrs. Grunwald ended in disappointment, but that's not the only discovery Spoby made in Ravenswood. Yep, another Tuesday night, another headache. Let's review what went down in Rosewood — and Ravenswood! — this week.

What did Spencer and Toby find in Ravenswood? A whole lot of creepy! First of all, what Instagram filter is Ravenswood taking place in because it just looks like a town void of color, sunshine, and happiness. There are ravens everywhere (and they occasionally fall from the sky), and not to mention a giant cemetery where the entire town congregates once a day. Yeah, it's creepy. Oh, and Shana and Jenna were there. Did they manage to get to Mrs. Grunwald first and threaten her not to give Spencer any info? 

Speaking of Spencer, the Liars aren't exactly happy with our resident bookworm after Mona tells them that Toby gave the lair back to "A." For some reason, Toby still can't tell the Liars the truth. He's afraid "A" will use it against him. 

Meanwhile, Aria decides to help one of Mike's friends (Connor) with his English homework. Why? Who knows! Did he need a friend? As Aria is seeing him off after a tutoring session, he just swoops in and kisses her. It last less than a second, she pushes him off, and promptly opens the door for him to leave. He later spreads the news of their "make-out sesh" all over the school! When Aria confronts him about his lies, Connor throws Ezra in her face and calls her a slut. Oh snap. Ezra saw the whole thing, but when he confronts Aria about it, she brushes him off. 

Instead, she goes to Mike, who apologizes for giving her attitude. He then takes his revenge on Connor by destroying his car. You go, Mike Montgomery. 

Last, but not least, after a poorly executed plan from Emily (will these girls ever realize that "A" is always watching?), Ashley Marin is arrested for Wilden's murder — after her prints were found on the murder weapon and the bullets. It's time to call, Mrs. Hastings — now.
