My prediction is that Maya is the new person sending texts. The famous PLL quote, "Did you miss me?" is supposed to be repeated in one of the future episodes. I think that Maya isn't actually dead. I think she will come back and say "Did you miss me?". We never actually saw a body and there was no funeral! Her life is kind of a mystery. We didn't know anything about her family! The only thing we new is she lived in Alison's old house and how her father proposed to her mother. We never really knew what she was capable of. She was gone for so long when she was sent away and maybe something happened when she left that we don't know about! She acted a lot quieter and not exactly the same person she was when she came back. But Alison, Spencer, Hanna, Aria, or Emily could have said "Did you miss me?" Coming back and seeing their friends for the first time in forever. When Emily found out about Maya, Emily's mom said, "they THINK it is Maya". We were never told they found out it was Maya. Even if they did, they thought Bethany Young was Alison's body, so they could be wrong again. When the girls were kidnapped and were at Charles' party, someone was controlling the music and lights. We know it wasn't Mona or A because they were together it couldn't of been Sara because she was roaming the halls. Maybe someone else has been working with A the whole time, like Maya. We also saw someone walk into the room to A. Sara was still roaming the halls. I think someone else was working with CeCe the whole time and CeCe knows who is sending them text in the new episodes. 6x11-6x20.
