Pretty Little Liars Pilot Revisited: Ezra's Big Clue and 19 Other Crucial Moments

Pretty Little Liars

The 100th episode of Pretty Little Liars is almost upon us, but before Tuesday’s milestone hour arrives (ABC Family, 8/7c), TVLine is going back — like, way back — to reflect on how it all began.

Before Aria knew about Ezra’s secret book, before Emily confessed her love for the ladies, before Caleb ever stepped foot into Rosewood, Pretty Little Liars was a simple pilot about four girls receiving suspicious texts from their (presumed) dead friend. And that’s how far we’re going back.

We’re also having some fun with a few of the things that have changed between Episodes 1 and 100, from the girls’ thoughts on “A” (Emily almost went to the authorities immediately) to the actors playing fan-favorite characters (Keegan Allen wasn’t always Toby).
