Now that Mona has confessed to killing Wilden, that means Ashley Marin can go free, right? Nope, it's not that simple, as we learn in this sneak peek of Season 4, Episode 9: "Into the Deep" (August 6).

In this clip of the episode, Spencer's mom has some good news, some bad news, and some more bad news for the Marin family. The good news is that because of Mona's confession, enough doubt has been created for the judge to agree to set bail for Ashley. The bad news is that her trial is still going forward, unless evidence can be found to back up Mona's tale.

The more bad news? Bail has been set at $1 million. Yeah. Not so helpful after all.

Here's the official synopsis of the episode:

Paige throws Emily a surprise birthday party with even more surprising guests — Jenna and Shana. But it’s “A’s” actions at the party that lead to the biggest shock of all. Mona’s selfless act provides Hanna and her mother with their first bit of good news, but sends Mona down a familiar path. And Ezra gets some distressing news from Maggie regarding her and Malcolm.

Meanwhile, Aria and Jake (Ryan Guzman) continue trying to define their confusing relationship. And Emily meets with a world class coach in a last ditch effort to salvage her swimming career.
