Sasha Pieterse Then; Sasha Pieterse as Alison DiLaurentis

Now, as the devious, secretive, and (oh, yeah) murdered Alison DiLaurentis, we only get to see Pieterse in flashbacks, or at least until recently when she's been spotted in the flesh... Or has she? She keeps us guessing as to what really happened to Alison.

Keegan Allen Then; Keegan Allen as Toby Cavanaugh

Look at those baby blues! Allen shines as the enigmatic Toby Cavanaugh—half-brother to Jenna and on-again, off-again love of Spencer. After his temporary involvement with the A-team is revealed in Season 3, Toby disappears, only to be found alive by Mona which leads to a more-than-friendly reunion. In Season 4, Toby focused on uncovering the motives behind his mother's suicide... or murder.

Lucy Hale Then; Lucy Hale as Aria Montgomery

An accomplished singer, Hale had dreams of making it big in the music world before landing roles in movies like Sisterhood of the Traveling Pants and shows such as Privileged. Now one of the leaders of the Liars gang, Hale gets plenty of time to flash her wide eyes as Aria Montgomery on the hit show. After being rescued by the mysterious "Red Coat" from the burning Lodge, Aria's got her hands full sleuthing and snooping around for answers... Is Alison alive or dead, and whodunnit?

Troian Bellisario in 1998; Troian Bellisario as Spencer Hastings

Bellisario has been enchanting audiences since she was a small child, racking up multiple entries on her resume since 1988. As the type-A perfectionist Spencer Hastings, Bellisario always seems to be uncovering major drama, or causing it herself... a stint on the A-team and crushing on her older sister's boyfriends? She's anything but perfect.

Then; Ashley Benson as Hanna Marin

It's obvious from this childhood photo that Ashley Benson, a.k.a. Hanna Marin, was destined to be a star. Season 4 proved to be more than mysterious for Hanna, given that she and Mona think they saw Alison DiLaurentis and two friends have gone missing and could be dead.

Chad Lowe in 1983; Chad Lowe as Byron Montgomery

The younger brother of Rob Lowe has done anything but hide in the shadows. Chad won an Emmy for his portrayal of HIV+ Jesse McKenna on Life Goes On before embarking on a successful career directing and guest-starring on shows such as Bones. Even though he’s not one of the Liars, Aria’s dad has some pretty big secrets of his own.

Holly Marie Combs in a 1991 Junior Yearbook Photo; Holly Marie Combs as Ella Montgomery

Combs saw more than her share of supernatural trouble as the star of Charmed, but that pales in comparison to what her on-screen daughter gets involved in on Pretty Little Liars. Ella Montgomery struggles to move on after divorcing Byron, which is a lot considering she also has to keep an eye on Aria.

Ian Harding Then; Ian Harding as Ezra Fitz

This German-born actor was cute from the start! Although he’s arrived fairly recently to the show business world, he's the perfect blend of sensitive teacher meets off-limits hottie, Ezra Fitz—even though he did seduce one of his students.

Shay Mitchell Then; Shay Mitchell as Emily Fields

Mitchell was all about the attitude as a cute kid but shows her reserved side as Emily Fields. Her nuanced portrayal of Emily’s homosexuality makes the character unlike most gay stereotypes on television—but sweet and shy doesn't mean she's a flower... Emily is a highly competitive swimmer and willing to do what it takes to protect her friends and lovers from the threats of the A-team. Unless of course she's in on it.
