Aria Marie Fitz (ńee Montgomery) is a fictional character in the Pretty Little Liars franchise created by American author Sara Shepard.

[1] In the book series, Aria is described as gorgeous, tall, lean with short blue-black hair, startling ice-blue eyes and an angular face.

While also commenting on her style: "She’s sort of all over the place… she’s the quirkiest one and just put miss-match pieces together and mixes vintage stuff with modern things… very funky… very creative.".

She later finds that after all her time in Iceland, formerly overweight Hanna is now thin, glamorous, and best friends with former nerdy outcast, Mona Vanderwaal.

She drops her brother off at lacrosse and stops off at a Bar and Grill, where she meets a man named Ezra, who mistakes her for a college girl and informs her that he will soon be starting a new teaching post.

In a conversation with her father, we see flashbacks of Aria and Alison catching her dad making out with another woman in the back of his car.

Aria begins to reunite with her old friends, mainly Emily, at school and discovers that Ezra is in fact her new English teacher, Mr Fitz.

However, they rekindle their romance at Ali's funeral, which is held after her body is discovered under the DiLaurentis' gazebo, which was being ready to build right before her disappearance.

They try to block them out of their lives by putting blockers on their e-mail accounts and their cell phones, but “A” appears to be too smart, even breaking into Spencer's house and ends up sending a detailed letter to Aria's mother, Ella, telling of her husband's affair, which leaves Ella devastated, and Aria guilty for keeping it from her.

Aria's parents argue and eventually separate over her father's affair, with her mom moving out of the house and into an apartment above her art gallery.

She declines at first, but eventually accepts when the school's SATs are cancelled and they have to take shelter due to a hurricane warning in which Ezra makes his return and tells Aria that she was all he thought about.

In the beginning of season two Aria's relationship with Ezra is on the verge of ending due to the revelation of his ex-fiancée, Jackie, working at the same college as him.

Mike continues to break into houses and gets arrested, but is released when Aria's parents come to pick him up at the station.

In the twelfth episode "Over My Dead Body", the liars receive a large box with chucky dolls inside.

Ella thinks Ezra is talking about Spencer and tells him that the Hastings parents will ruin him if they find out about the relationship.

After he is fired, he tells Aria that he can't teach in that town anymore and must find a place where he can before they can start dating again.

In the Halloween episode Aria is kidnapped by A and nearly killed after being locked in a box with a dead Garrett Reynolds (Yani Gellman) and nearly being pushed out of a moving train onto the track, luckily Hanna, Spencer and Emily come to the rescue.

She nearly gets hit by a car and decides to take up karate, where she meets a cute instructor named Jake and starts developing feelings for him.

A kidnaps them on their way to a prison in the Season 5 finale and traps them in his dollhouse, but the girls outsmart him, find Mona, and try to escape.

She finds the color applicator in the Hollis College's darkroom, which leads her to befriending a fellow photographer, Clark, and they soon become quick friends.

During this difficult time, Ezra supports Aria and she starts helping him write his book as he comes to terms with Nicole's loss.

In Along Comes Mary, Ezra proposes to Aria who says she needs to think about it because of her part in the Rollins accidental murder when he is hit by Hanna Marin's car.

Sydney says that leaving Alison and coming to meet them was the first step towards Aria earning "A.D.'s" trust, but she still has a long way to go.

In The Glove That Rocks the Cradle, Aria continues to work as the helper to "A.D." and eventually puts on the black hoodie and breaks into Alison's house as "A.D." on their behalf.

In Driving Miss Crazy, Aria's work as "A.D." helper continues when they send her to the Hastings residence to deliver a phone with a message that will play through their Bluetooth speakers.

In "Till Death Do Us Part", it has been one year since the last episode, we first see Aria and Ezra on the set of a film studio where their book is being made into a movie.

In episode 5, Tabby and Imogen break into Sullivan's office and go through the private practice files, finding some on Aria, Hanna Marin, Spencer Hastings, and Emily Fields.

[12][13] Her romantic teacher-student relationship with Ezra Fitz was controversial throughout the series, especially due to it being romanticized and rarely addressed as problematic in the show.

[14] Many critics have panned the representation of Aria as an equal in the relationship, with reviewers stating that she was a victim of statutory rape all throughout the series.
