I am one of those die hard "Pretty Little Liars" that has watched the show since the beginning. If you're one of these fans, you know that the past few seasons have had many unexpected twists that have sadly lead to many plot gaps and unanswered questions. Even with these outrageous plots, I refuse to stop watching before the final season ends because I have invested so many hours into the show. Here are just a few of the plot gaps and questions I hope season 7B addresses.

1. Who killed Sara Harvey?

There is a lot of confusion about Sara Harvey's character and her involvement in torturing the girls. No one really knows her motive for targeting them or what her role is in the show. However, Sara's connection to Charlotte must have been important since she was also murdered. Like Charlotte's killer we still don't know who killed Sara.

2. What is Wren's role in all of this?

Wren has been a reoccurring role throughout the entirety of the show that fans have grown to love. However, our love for Wren has slowly disappeared. He is somehow connected to Elliot Rollins which leads fans to believe that he might be involved in blackmailing the girls.

3. Does Melissa know about her family's secrets?

Melissa has always been a sketchy character throughout the series and always seems to be involved in everything. Spencer just recently found out that her biological mother is Mary Drake which makes us wonder, did Melissa already know this?

4. How does Lucas fit into all of this?

Lucas has always given off a creepy vibe. His hatred for Alison and his ulterior motives make fans wonder if he is more involved in torturing the girls than he lets on.

5. Who killed Charlotte?

In season six, Charlotte is released from Radley and lives with her sister Alison. Unfortunately on the first night that Charlotte was released, she was murdered. The identity of her murderer is still unknown, but the five girls are now being tortured by a new "A" called A.D. who wants to find out who killed her.

6. What happened to the eggs Emily donated?

Emily donated her eggs to earn extra money since she blew through all of her college fund. Of course A.D. somehow was able to steal her eggs since the impossible always happens in Rosewood.

7. Are we missing any information about the baby Alison is pregnant with?

During season seven, we find out that Ali is pregnant, but there are so many questions that have accompanied her baby's identity. Is the father actually Rollins? Is Ali the biological mother or were Emily's stolen eggs implanted in her?

8. Who is AD?

The most important question that has to be answered this season is who is A.D. There are many theories on the internet that speculate A.D.'s identity, but with all of the unexpected twists of this show there is no telling who it could be.
