<p>I have a sneaky suspicion that Jenna Marshall is Bethany Young and she killed Charlotte Dilaurentis.Firstly, Jenna and Charlotte became very close all of a sudden with Jenna stating that she was like a "Celebrity" to Charlotte, although Charlotte threatened to scratch her eyeballs out in season 3. I feel that Charlotte somehow found out that Jenna was in fact Bethany Young and wanted revenge or blaming Charlotte for killing Toby's mom.I think Jenna was occasionally admitted into Radley due to a mental illness, which only got worse after her accident. I also believe Charlotte Dilaurentis gave Ali the idea of throwing the firework into the Cavanaugh's shed, knowing Jenna would be there. (Charlotte pretended to be Toby and wanted to meet up). Anyways, Jenna ended up blind that night and was sent to Radley after a breakdown and for what happened to Toby! Throughout her stay in Radley and the Blind School,Jenna met a young student doctor named Wren Kingston (who did rotations in both hospitals). and they became close. Jenna told him everything the girls had done to her and he felt sorry for her.
</p><p>That Night she broke out of Radley to get revenge on Ali and hurt her mum, hurting her mum would really kill Ali and Charlotte, who Jenna had already suspected had something to do with her accident. Although Jenna had her suspicions, Charlotte passed blame onto Ali,thinking she would be saf and that Jenna was too scared to harm her. She thought Ali's parents would protect her. Jenna stole Charlotte's clothes and disguised herself in a blonde wig (allowing Kenneth and Radley to believe Charlotte killed her). Throughout the night, Jenna met up with Garret to get the video of her and Toby destroyed before Alison leaked it! Ali would suspect Jenna if anything happened after she threatened her in the Blind School! But Charlotte "killed" Alison, thinking she was Jenna! Then Jenna got away with her plan! Alison stopped and Charlotte suffered as well! Charlotte then wanted to get revenge on Jenna, and that's why Jenna was so scared of her! She knew if she wasn't protected by Shana, Wren or Melissa, Charlotte would kill her! When Jenna was released, she still wanted to get revenge on the girls. However, during the time jump after Charlotte was sent to Welby, Jenna went to visit her. Charlotte initally wanted to gloat about Charlotte being locked up for good, but then she felt bad for her and what the liars did. Charlotte hated Jenna, but saw their friendship as a way out of the hospital!Jenna then met Archer and got him into Welby through her old doctor friend, Wren Kingston. Jenna began to think Charlotte was using her and she began again to think she had something to do with her accident and she wanted Archer to investigate and see what really happened.Archer was originally a spy for Jenna, but he fell for Charlotte and this annoyed Jenna 'cause she was falling in love with him. Jenna eventually found out that it was Charlotte who got the girls to blind her. She then devised a plan to make Charlotte and Archer believe she could get out of Welby and when she was released, Jenna would get revenge!
</p><p>Jenna also encouraged Archer to get with Alison to further develop her alibi if anything went wrong in her revenge plan. She wanted Charlotte to feel the hurt and pain she felt when she was blinded! She wanted to make Charlotte angry with Alison and give the police a reason to suspect Alison. Jenna rang Charlotte on the night of her murder and wanted to met up with her. Charlotte told her that they needed to end their friendship and it became clear to Jenna that Charlotte was using her. Jenna was livid and went to the Dilaurentis house to discover that Archer was there, but Charlotte and Alison weren't. When Jenna asked Archer to be with her, Archer told her that he didn't love her. That he wanted to be with Charlotte. He wanted to marry her. Jenna took a handful of Charlotte's flowers and left. Jenna met up with Charlotte at the church and offered her the flowers as a peace offering . Jenna then revealed tht she knew Charlotte was the one who was behind blinding her and she sent Archer in as a spy and Archer loved Jenna. This infuriated Charlotte and she attacked Jenna. They had a fight and when Charlotte turned her back -without thinking- Jenna snapped and stabbed Charlotte in the back of the neck with her stick. When lifeless Charlotte back onto Jenna, Jenna thought she was attacking her again, so she pushed her with brutal force! This knocked Charlotte through the window and to the ground! It's only when she felt the blood on her hands did Jenna know she killed Charlotte. Jenna never wanted to murder her, she just wanted to teach Charlotte a lesson and show her who's boss! Jenna then left town , but came back to pretend to search for answers, when she really needed protection and looked for forgiveness from Toby so he could protect her! Jenna is pretending to be on A.D's team because she is scared and wants the suspicion off her! She is blaming the liars as a form of revenge and she wants them to suffer. Sara was looking for who killed Charlotte and when she was onto Jenna, she was going to tell A.D, but Jenna got Noel Kahn to kill Sara, so she wouldn't spill her secret.
</p><p>
</p><p>BTW!
</p><p>When Spencer was accused of killing "Bethany", it was a part of Charlotte's plan to get her into jail. Charlotte paid off multiple people within Radley, UPenn and Rosewood P.D to infiltrate Bethany's records and get Spencer into the Dollhouse along with the other liars. Mona thought she killed Bethany that night when in fact, it was Sara Harvey she hit and Melissa buried her. Sara then got out and Charlotte looked after her and helped her.Sara was eventually brainwashed into believing that she owed Charlotte and did her dirty work for her such as breaking into Hollis Medschool and stealing a cadavar(With the help of Wren Kingston), making everyone think Bethany was dead! Charlotte then used it to blackmail Mona and Melissa into her with the A-Game! Jenna also used "Bethany's" death to get Mona to say she was the one who rang Charlotte the night she died. Jenna also blackmailed Melissa for money so she could pay Noel Kahn to work for her,protect her and to be her eyes and ears!
