Aria: "Tell me the truth."
Ali, verbatim: "If I tell you the truth, you don't have to believe it."

Aria: "Did my father kill you?"
Ali: "I'm not dead. Also, don't drink that poisoned tea. Meredith's looking for these pages, too. I gotta go."
Aria: "Well, if you gotta go. Who am I to question you at this point. I am high as hell."
Ali: "You know why I picked you, right?"

She winks, she vanishes. Love that girl! When Aria wakes up the doll's where Ali left it, by the bedroom door. She thinks better of drinking her poisoned tea, and quickly figures out that she is locked in her bedroom and that Meredith has trapped her, which I guess takes precedence over the fact that she was just visited by a ghost, who moved her shit around.

CLONAZEPAM IS A CLASS 3 MEDICATION

Emily: "Sorry about your mannequin-related injury. There's a boy on the swim team who is like double-jointed, so if he'd been attacked by mannequins probably it wouldn't have worked out like this."
Hanna: "Emily, your brain works a weird way."

They pass a drugstore just at the time that Meredith is flipping out on the guy.

Meredith: "But I need more Klonopin! It is to calm my nerves!"
Guy: "Clonazepam is a class 3 medication, ma'am. Get your doctor to call in a refill."
Meredith: "BUT MY NERVES."

She stacks up a shitload of OTC allergy meds instead, making the Liars's eyeballs go wide. While Aria tries to break out of her own bedroom, Hanna and Emily use the internet to figure out what Klonopin is for, which is to make Aria very sleepy. She doesn't notice them lurking, which is good.

Over at the Montgomery house, Aria has given up on freedom, and instead smashes a mirror and wraps her hand with a nearby Aria Scarf to create a makeshift shiv. Which is so very wonderful. I can't say I've ever been prouder of the girl. "Oh, feed me poisoned tea? How about a jagged mirror shard to the face, you like that?" That's some Spencer Hastings-quality zero-to-sixty shit right there.
