Hit and Run, Run, Run - S7-E4

Revealing mistake: When Emily gets a phone call from Spencer, the answer button is still visible when she puts the phone to her ear, meaning the phone should actually still be ringing.

THGhost

Hush Hush Sweet Liars - S6-E20

Revealing mistake: When Aria calls Spencer from the Lost Woods Resort, Spencer's phone is not in Call Mode.

THGhost

Game Over, Charles - S6-E10

Revealing mistake: After the flashback to when the girls first met Cece at The Brew, she looks at them through a window outside when she leaves. If you look closely at Cece's hair, you'll notice a green glow, revealing that she's on a green screen. This explains why the image of the girls through the window doesn't look quite right. Cece is also wearing a different dress.

The Melody Lingers On - S5-E23

Continuity mistake: When Ashley and Ted are in the kitchen talking about Allison's trial, Ashley's hands go from raised to down by her sides and back again between shots when she says "It's not a way to start a life together."

To Plea or Not to Plea - S5-E22

Revealing mistake: When Emily calls Varjak's number from the Tony's Pizza receipt, her phone says that it has no service - meaning she should not be capable of making any calls.

THGhost

Pretty Isn't the Point - S5-E20

Continuity mistake: The pizza slice that Hannah is eating when her mum starts talking to her and Emily in the kitchen jumps back onto her plate between shots. Her arms are also suddenly folded.

The Blond Leading the Blind - S2-E17

THGhost

Through Many Dangers, Toils, and Snares - S2-E14

Continuity mistake: When Emily circles the word "yes" on the chalkboard, the way the circle is drawn changes between shots.

THGhost

Show generally

Revealing mistake: Judging by the interface, the video of Jenna and Toby sleeping together is played through Windows Media Player. When this program is playing a video, the big blue "Play" icon becomes a "Pause" icon. But whenever the video of Jenna and Toby is playing, the "Play" icon is still showing. It's obviously not an actual video being played.

THGhost

A Person of Interest - S1-E19

Continuity mistake: On the video of Ian supposedly killing Alison, we see her arm fall to the ground with her "Alison" bracelet visible. But in a later scene where Emily watches Ian put his bag in the athletics room, we cut back to the video and Alison's arm suddenly has a sleeve covering up her bracelet. When we see the video again later in the series, her bracelet is visible again.

THGhost

Touched by an 'A'-ngel - S2-E10

Revealing mistake: At the end of the episode, Emily receives a phone call from Dr. Sullivan which she does not answer. Look at her phone when she hangs up: Not only does she simply press the "hang up" icon when the arrow indicates she needs to slide it to the left, there is also a magnifying glass symbol at the bottom indicating that it is in fact an image file on the screen and not an actual phone call.
