Alison killed Charlotte and is framing the liars for it. Meanwhile, Uber A is Charlotte's TWIN/the 'he' from 6x10!
Alison killed Charlotte. Her begging the liars to say “I’m not afraid of Charlotte, release her” was all part of her plan to set them up. With all of them saying ‘release her’ and one of them saying “I won’t feel safe with Charlotte released”, it looks like they wanted her released so one of them could kill her - the liars not realising this is how it sounds at the time of giving their speech. “You don’t know them like I do” - Alison knew Aria would say the truth which further makes them look guilty of wanting Charlotte released to kill her as a hate for Charlotte still remains. Alison still never forgave Charlotte for all that she did to her, hence she wanted to kill her but had no problem with throwing her friends under the bus for it. That will be a big twist, that actually deep down, Ali doesn’t fully LOVE the girls as the girls love each other. Yes friends, but not loving friends. She’s a user. Let’s not forget her manipulative, bitchy days of the seasons 1, 2 and 3 flashbacks. She was cruel (kissing Emily was just for practice, threatening to tell Melissa about Spencer and Melissa’s boyfriends, blackmailing people for money, threatening to break up marriages, those remarks about Hanna’s weight, Loser Mona) - and somehow all that nastiness just went away when she came back alive in season 4? NO! She was putting on a fake act when she came back alive in season 4, so her friends can help her bring her home and safe away from A. She was using them because she needed them. The true her is; yes friendly, but NOT loving, and she had no problem with framing the girls for Charlotte’s murder. Again, using them!
Alison isn’t evil though - she was technically doing everyone a favour as none of the liars wanted A to live happily ever after but Ali didn’t want to take the blame. Remember, Ali had it the worst from Charlotte’s actions. Remember, Charlotte ‘killed’ her which made Alison go in hiding for 2 years of her life. Then she was framed for (Mona’s) murder, despite CeCe having her reasons, and was generally still pissed off at Charlotte playing that A game with her as if she’s a doll.
Charlotte ‘killed’ Ali and played that A game with her - now Ali got her true revenge. Ali staying in Rosewood over those 5 years to help Charlotte was all part of her alibi - “but I love Charlotte, I helped her over 5 years, I’d never kill her!” and if she’s really that twisted… she may go further to actually say “it was those girls who said they can release her from the hospital so they can kill her!”
Alison isn’t Uber A - she is just the killer. A clue from the writers that Ali is the killer: the roses! Whilst how Charlotte actually got to holding the rose, I feel is irrelevant, I feel this is just a clue from the writers saying “Charlotte had a rose in her hand whilst dead, but you’ve seen that rose before in Ali’s house, connect the dots, there’s your clue”.
Now, Marlene has confirmed (twice) that there is a twin on the show. One of her confirmations is here, and yes it is real, and no she wasn’t lying by saying we will find out soon:
Uber A is Charlotte’s twin who has NOT transitioned as Charles transitioned to Charlotte. Credit to @night-visions-imagine for messaging me and proposing that Charlotte’s TWIN is the ‘he’ from the end of 6x10!
Season 6 will end where the liars find out that Charlotte has a twin who never transitioned; is a boy. The liars know that this person is after them because they look guilty for having killed Uber A’s twin/Charlotte, thanks to Ali for setting them up. Hence “he’s coming for you” in 6x10 - that scene hasnt taken place yet, and when it does in the season 6 finale, it’ll be because the liars figured out Charlotte has a (male) twin, and suspects Ali/the liars for having killed his sister, Charlotte.
So there’s another 1.5 seasons of Pretty Little Liars for you! Charlotte’s twin getting revenge on Ali “and the liars” for killing Charlotte. Yes, the liars didn’t do it, but Ali made it look like a group effort that they ALL contributed to it. And so another A game begins to get revenge…
