On June 10, the fifth season of Pretty Little Liars airs on ABC Family at 8 p.m. At the end of last season, the show left us with one of its best cliffhangers yet, leaving viewers with one looming question: who shot Ezra?

The show has brought its viewers on a wild rollercoaster ever since it first aired in 2010. Four years and four complete seasons later and we're all still wondering who A is and what happened to Ali the summer she disappeared.

There have been so many creepy and shocking moments on Pretty Little Liars that it would take a Top 30 just to cover half of them. But in honor of the new season premiering on Tuesday, here are the top 10 Pretty Little Liars moments that stood out the most in the past seasons.

10. Ezra being Aria's Teacher
In the first few minutes when we meet Aria in season one, she was sucking face with a hot older guy in a bar. How a high school freshman got away with sneaking into a bar and convincing a college graduate that she was over 18 is still a mystery to us. But that wasn't even the most shocking part of her steamy bathroom make out session. When Aria walks into English class that Monday, who is at her teacher's desk? Ezra himself--the man she made out with just days before.

9. Hannah getting hit by A's car
After getting uninvited to Mona's party at the Rosewood Camping Grounds in season one, Hannah opts to stake out and keep an eye on her friends from afar to help protect them from A. Hannah sees someone she thinks is A writing a message in the condensation on Mr. Fitz's car while him and Aria "talk" inside (see #8). After sending her friends a "I know who A is" text, Hannah is struck down by a fast-moving vehicle. As her friends are screaming for help they all receive a text from A claiming that Hannah "knew too much."

8. "I can see you"
Right before Hannah gets hit by A's car, she watches as Aria gets into a car with Mr. Ezra Fitz. As the two talk (and smooch), a hooded figure runs up to the car and writes "I can see you" in the condensation on the back window. If the message itself isn't creepy, then the shadow of the figure scrawling the message on the window while the oblivious couple make out sure is. What else can A see?

7. Ian's dead body disappearing
Season one is chock full of creepy scenarios, but Ian definitely takes the cake as the creepiest character. Engaged to Spencer's sister, it's revealed throughout the duration of season one that Ian not only had a short fling with Spencer but also with Ali around the time of her death and disappearance. In the second-to-last episode of season one, Ian and Spencer face off in Rosewood's church. With Ian's hands around her neck, threatening to throw her off the bell tower, it seems as though all hope is lost for Spencer . . . until a familiar hooded black figure storms in and saves her. The only downfall (no pun intended) is that this hooded figure threw Ian off the bell tower, thus killing him instead of Spencer. Then, when the police finally showed up, they announced that there was no body to be found. Later it's revealed that Ian ran away from the scene, only to be found dead (for real this time) with a self-inflicted gunshot wound to the head. The strangest part? His suicide note was made up of the texts that A was sending to the girls.

6. Spencer going cray-cray
Spencer is probably one of the strongest characters on the show, so it was both terrifying and amazing to watch her break down and go a little crazy in season three. After not only being betrayed by Toby, her boyfriend, but also seeing a dead body that was made up to look like Toby, Spencer found herself in Rosewood's mental hospital, Radley. There we got to watch Spencer spiral out of control and slowly regain control over her life. On top of that, we got to see what Radley was really like from the inside.

5. Spencer going cray-cray p.2
After the downward spiral that Spencer went through in season three, you'd think that she would be able to keep it together after her recovery, right? Wrong. In season four, Spencer goes cray-cray in a whole different way. She gets hooked on Adderall, a drug that helps people suffering from ADD/ADHD. As she slowly starts losing it from popping too many of these pills at once, it's revealed that Spencer was also taking these pills the summer Ali disappeared. Perhaps there's a connection between the two?

4. CeCe Drake
Everything about this girl is creepy and weird. The fact that she looks like she could be Ali's twin, to the fact that she talks just like Ali and that she always seems to be connected to the worst people in Rosewood. Everything about CeCe is sneaky -- she seems to never be able to tell the truth. In season four, Mrs. DiLaurentis describes CeCe and Ali's friendship as "toxic" and that they "wore each other's personalities." In the season four finale, CeCe reveals to the police that she knows who killed the girl who is currently in Alison's grave and confirms to the police that Ali is still alive. How many other secrets are you keeper of, Cece? Maybe you'll give us more answers in the upcoming season.

3. Aria locked in a box with Garrett's dead body
I think everyone was relieved to see creepy Garrett kick the bucket, but poor Aria had to survive a train ride stuck in a locked box next to his dead body. Every year, after the summer finale of the new season, the creators of Pretty Little Liars premiere a Halloween episode and season three's Halloween episode definitely took the cake as the most thrilling. After being drugged by an unknown person (let's be real, it was definitely A), Aria wakes up locked in a box and comes face to face with a dead body. It was probably one of the most stomach-churning moments in PLL history.

2. Mona is A
The biggest reveal in reveal history! The clues were building up for two seasons, but the most shocking part about the reveal of Mona being A was the first glimpse of "Red Coat." In the season two finale, when Mona was locked away in Radley Sanitarium, she looks up at a figure in a red coat and confirms that she did everything this person asked for. So with the reveal of Mona being A it was also revealed that Mona isn't actually A, she's just one of A's minions. Plot twist!

1. Ali's hand
We've known for a while that Ali was buried alive -- the police report that there was dirt in her lungs, meaning that she suffocated to death. In the final scene of the season three season finale, a flashback is shown where Ali attempted to crawl out of the dirt on her own. In this creepy scene, Ali's hand pops out of the ground and grapples around for something to hold onto. And then something incredible happens; someone else's hand enters the shot and grabs ahold of Ali's hand, pulling her out of the ground. Someone (it's revealed later who that someone is) has known of Ali's existence and has been helping her stay hidden this whole time.
