The tom sawyer theory by lolitaria

Hello! 
This is the Tom Sawyer theory by lolitaria
At alisons memorial, the girls recieve a text that says “do it right. I’ll be watching just like Tom Sawyer.” Some people think this clue is just a literary/book reference and think it points to Ezra being -A. But in the book the adventures of Tom Sawyer, Tom attends his own “funeral”. Tom was believed dead. But he actually watched from the gallery. This isn't about Ezra. It's about alison. She’s not dead ! Alison is alive.
