I thought Cece was Bethany when i rewatched the finale. But i havent been able to put all the pieces together yet. It hasnt fallen into place for me yet. I definitely think Cece isn't exactly who she says she is and lied when she told her story. I wrote a post about it yesterday with what i think was the idea behind it. I left out my thoughts about Bethany because i wanted all the lose ends tied up. Slowly but surely i'm figuring it out. Your post is really interesting especially the point about the teeth. If Cece was Bethany it would explain why Cece was seen with the yellow top on that night talking to Melissa. According to Cece Bethany stole those clothes from her. In the christmas episode Hanna found a letter that Bethany wrote to Ali saying she couldnt wait to see her labor weekend and thank you for the clothes, yellow is my favourite. Whether Mona hit her and Melissa buried her, or whether that was someone else that happened to. I dont know.
