SINISTER SPA

Nice Lady: "...Okay, ready for your massage?"

A tumbler on the side table has ice water in it, with A written in the ice water sweat. It is the scariest glass of water that has existed since a Tyrannosaurus Rex was cloned from its DNA that time.

Emily's Mind: "EEEEEEEEEEEEEEEEEE!"

Emily's Phone: "You know how I predictably freak out every time you get close to telling Therapy Anne about me? Maybe you should think about that, because my hands were just totally around your neck. I am not fucking kidding. -- A"

Emily's Mouth: "AAAAAAAAAAAAAH!"

FITZ SHOWDOWN II

Spencer abruptly jumps into Ezra's car with him and slams the door. This scene is amazing because they are both good actors, because Spencer could create chemistry with a block of wood, and because Ezra has every reason to be terrified of her. Also the dialogue is outstanding, to wit:

Spencer: "Okay, there's something that I need to tell you. But before I tell you that, there's something else that I need to tell you."
Ezra: "...Okay?"
Spencer: "I know about you and Aria."
Ezra: "Excuse me?"
Spencer: "Ezra, you don't... Sorry. Mr. Fitz."
Ezra: "Better, thank you..."
Spencer: "Listen to me. Aria's in danger, okay, she's been hanging out with Jason DiLaurentis..."

Ella: "That looks suspicious to me, I wonder if all those rumors were true. Spencer is kind of like a scary old man, after all. I can see it. I wish instead of Spencer that Ezra Fitz was dating me, though. I am having all kinds of thoughts. I'd better talk to my daughter about this. She never acts totally sketchy every time his name comes up."

DILAURENTIS KILLING FLOOR

Jason, literally: "Hey, that box of worthless female mementoes is in my crawlspace. Just come around here to the back of my house and I will show it to you."
Aria: "Um..."
Jason: "There is candy. Also a kitten."
Aria: "I think I will just wait here in broad daylight where I am visible from the street."
Jason: "You're such a jokester!"
