Talk:Taking This One to the Grave/@comment-4146635-20140831033958

I'm not the best with theories but I just thought of this one. Maybe Sara Harvey is Ali's twin but maybe when they were younger, the two fought a lot, possibly Alison bossed Sara around a lot and bullied her. Eventually, when Sara Harvey grew up (somewhere around when she was a teenager), she left her family, moved to Courtland, and changed her name. There in Courtland, since she always felt inferior to her sister, she decided to take on the superior role to make herself finally feel like she was worth something and to start off her new life. Maybe, later on somewhere along the line, Mrs. DiLaurentis had an affair with Bethany Young's dad and that's how she became connected to Bethany. As a way to kind of replace Sara, Mrs. D. spent more time with Bethany. Maybe, she bought Bethany a lot of clothes that Ali would wear so they could be like twins.

So here's my theory about Ali's murder. Maybe, Sara Harvey returned to Rosewood and hit Ali on the head with the rock (maybe they were just fighting or something like that, I wouldn't think she went to Rosewood to hit Ali with a rock). Then Mrs. D. burried Ali to cover it up and, since she still loved Sara, she didn't want her to get in trouble. Then, after Sara found out about Bethany Young, her "replacement," she freaked out and hit Bethany on the head with a shovel, which may be unknown to Mrs. D. Maybe she dug a hole for Bethany but she heard someone coming (Spencer) so she ran away. Then, Melissa found Bethany, saw Spencer with the shovel and thought she killed her so Melissa pushed Bethany in the hole and burried her alive. Then, after Sara realized she "killed" two people, she ran away the next day and went into hiding so she wouldn't get caught, which explains her going missing. Then, eventually, after she found out Ali was really alive, she, more vengeful than ever, decided to take the A game from Mona and now she's haunting Ali and the girls.

I know it's been said that Ali isn't the one with the twin but hey, you can't trust these people, can you really? What do you guys think?
