1. The message the Liars received from A moments after they said they weren't going to Mona's party.
It seems so obvious now!
2. When she said this to Hanna:
She sounded just a little too serious...
3. The text she apparently got from A telling her that Hanna had liposuction.
Conveniently received right after she had fallen out with Hanna for missing their lunch.
4. The location of her party which made it oh so easy for the Liars to find A's clues.
Coincidence, it was not.
5. Her not-so-subtle choice of party wear.
The perfect distraction for anyone trying to hunt for A.
6. What happened to poor Hanna who had been disinvited from her party.
Mona sure did have a bad temper!
Could you tell Mona was A from this episode?
