One secret is already out: Aria's dad cheated on her mom.

What will A expose next on Pretty Little Liars? That's the question on the minds of viewers everywhere as we head into next Tuesday's new episode.

It's titled "Reality Bites Me" and the pair of clips below make it clear that at least two developments will be the focus:

1. Emily's burgeoning relationship with Toby;
2. Aria's parents having it over over Byron's affair.
