Ezra is -A part 4

Hello!
This is the Ezra is -A part 4 theory
In Season 1, Episode 16 (Je Suis une Amie) while Hanna is climbing in the library, a Toni Morrison poster is prominently shown on the wall beneath her... Toni Morrison is an American novelist, editor, and professor. Her novels are known for their epic themes, vivid dialogue, and richly detailed characters. The Bluest Eye is her first novel, The story is about a year in the life of a young black girl who has blue eyes.Who has blue eyes in pretty little liars? Toby and Ezra!

PLUS in one episode we can see written in the chuckboard something that looks like "Morrison"... There are no coincidences in Rosewood.
