Looks like Hanna has gotten herself and her mom into even deeper trouble!

Last week on "Pretty Little Liars," Hanna finds a gun in her mom's purse after successfully breaking into her room using only a hair pin. You go, Han! She thinks the best idea would be to go to a frat party at Cisero College, where Spence and Emily are on "college tours" to bury the gun. Well, it didn't turn out too well for Hanna, as we see as the episode ends that she leaves the frat party in handcuffs after the police find her burying a hole in the woods to toss the gun. Not your smoothest move, Hanna.

In next week's episode of "Pretty Little Liars," things get heated up as Hanna tries to explain why she had the gun, how she got it, and why she was planning to bury it since that makes her mom look even guiltier. As if Mona hasn't done enough, she spills a secret of Spencer's to the other Liars, which only leads to the group being upset with her.

Obviously "A" has to get involved again, as she tries to turn the tables when Emily tries to be a good friend and help Hanna get out of her catosphere . Aria puts on her "big sister" shoes and helps out a friend of her brother's.

Shauna decides to also make another un-welcomed appearance. I mean, when is her appearance ever welcomed anyway? She has been so sketchy lately.

Spoby decides to dig more into who lies on the "pink side of the phone," which ultimately leaves them to spooky Ravenswood.
