12 Things that we need to know by the finale of Pretty Little Liars.

Pretty Little Liars is an American teen drama mystery-thiller television series based loosely on the novels written by Sara Shepard. The show premiered on June 8, 2010 and it's last half of season 7 will pemeire April 18, 2017 for its final 10 episodes, premiering on ABC Family.

The storyline is set in a fictional town of Rosewood, Pennslyvania, following the lives of fours girls, Aria Montgomery (Lucy Hale), Hanna Marin (Ashley Benson), Emily Fields (Shay Mitchell) and Spencer Hastings (Troian Bellisario), whose clique crumbles after the disappearance of their leader, Alison DiLaurentis (Sasha Pieterse). One year Later, the four girls reunite as they begin recieving messages from an anonymous named 'A', who threatens to expose their deepest secrects, including ones they thought only their late friend Alison knew. At first they believe its Alison herself, but after her body is found, the four girls realise that someone else is ruining their lives. These are 12 things that need to be answered before the end of Pretty Little Liars.

1. Who is Uber A? There is someone sinister at the very bottom of this whole mystery: a figure who identifies as "A.D." But to what extent is this person involved? Does A.D. trace back to the beginning? Is there a reason we haven't heard of them until now? And how does "A.D." tie in with the Carissimi Group, Mary Drake, and Dr. Rollins?

2. Who killed Mrs. D? We know Jessica's twin, Mary Drake, is alive and well, but Mrs. DiLaurentis is still dead. Why did she die and who killed her? Was it Mary Drake, Dr. Rollins, "A.D.," or someone else completely?

3. How was Sara Harvey involved and who killed her? We first meet Sara Harvey in the dollhouse, but we later learn that there's a lot more to her. After revealing herself as "A", CeCe Drake (aka Charlotte) explains that Sara Harvey had previously dressed up as the Black Widow and Red Coat. The question is . . . why? What does Sara have to do with Charlotte and why would Sara help her in such huge and sinister ways? We have the feeling there's a lot we're not being told.

4. Who killed CeCe Drake aka Charlotte DiLaurentis? We know Charlotte was killed as soon as she left police custody; she gets thrown from the bell tower. There's plenty of suspects, but we can't help but wonder: are Charlotte's killer and Jessica DiLaurentis's killer the same person, or two different people?

5. How is Wren involved in all this? There's no way Wren Kingston is totally innocent. We really thought he could be "A" before Charlotte claimed the title. There was something so suspicious about his behavior as a doctor in Radley Sanitarium. Not to mention his shady phone calls, his conversations with Mona, and even the British accent of Dr. Rollins.... brothers maybe?

6. What is the Carissimi Group? We know our time with the Carissimi Group has just begun. In fact, Dr. Rollins reveals his marriage to Alison is all a sham to gain control of the company. But why? What is the Carissimi group and how is that connected to the Liars?

7. What is Eddie Lamb's Story? Perhaps the most troubling fact about Eddie is that he recognizes Aria when she goes undercover at the hospital. He remembers Toby from when he'd visit his mother. He works closely with Mona and Spencer when they stay in the sanitarium as patients. What does Eddie know? Does he play a larger part in this? And where is he?

8. Who are Spencers Parents? From the start it was believed that Spencer was a Hastings through and through. At the end of season 7a Mary Drake tells Spencer in fact that she is her mother. The real question is..... is this true? Does this make her related to CeCe aka 'A'? Is Peter her father? Or was she adopted and why did she never know?

9. Who is CeCe's father? Jessica DiLaurentis claimed to be CeCe's mother but was later revealed that she was taken from her sister Mary Drake but who is her father? Kenneth or some other lover?

10. What part does Melissa Hastings play in all this? Throughout the seasons Melissa Hastings has always been totally sketchy with the liars including her sister Spencer and we don't think she's comepletly innocent in all of this. What is her connection with Wren? Is she trying the hurt the liars? Why was she setting up the fire with Shauna and Jenna? and why so much hate for the liars?

11. How did the moms get out of the DiLaurentis' basement? At the end of season 6 we see the moms of the liars, get trapped in the DiLaurentis' basement and the next thing we know, they're not. Who came and got them out? Who locked them in to begin with?

12. Who couples are #EndGame? We all have our favourite couples over the seven season and theres been so many break ups and make ups but who will be end game? Ezria? (Ezra and Aria) Spoby? (Spencer and Toby) Emison? Emily and Alison) Haleb? (Hanna and Caleb) Paily? (Paige and Emily) Jaria? (Aria and Jason) Spaleb? (Spencer and Caleb)
