The Keating five will learn that not everything is as it seems while digging for new evidence in the Hapstall case during Season 2, episode 6 of ABC's "How to Get Away With Murder." When the show left off Annalise Keating (Viola Davis) and her five star students were hard at work trying to discredit the testimony of Caleb (Kendrick Sampson) and Catherine (Amy Okuda) Hapstall's aunt. They were able to dig something up, but had it thrown out after the judge ruled that it had likely been obtained illegally. The case will take yet another strange turn in the upcoming episode.

According to the synopsis for "Two Birds, One Millstone," the Hapstall case will remain front-and-center in episode 6, however, everything viewers have learned so far will be turned upside down. During their continued investigation the Keating five will find new information that suggests the killer may not be who they've suspected all along. ABC calls the new suspect "shocking," suggesting viewers won't see it coming either. In the meantime Annalise will take on another case, this time defending a transgender professor accused of having killer her husband. The new case will likely play out alongside the Hapstall case, but will not be the main focus of the show.

Although it is not mentioned in the synopsis, the show's title points to the fact that "HTGAWM" episode 6 may also center around Asher Millstone (Matt McGorry). For two episodes he has been shown meeting with his father and another attorney, plotting to come clean about the illegal activities he partook in while working under Annalise. Bonnie (Liza Wiel) catches on and decides to lie in an effort to save Annalise and the rest of the Keating five. She tells Asher it was her who killed Sam (Tom Verica) during Season 1, claiming that the others -- with the exception of Annalise and Frank (Charlie Weber) -- had no idea. While it appears that her plan worked briefly, Asher later tells her he can't continue on with a life of deceit. She breaks down and calls Annalise, telling her she failed the mission, at which point the seasoned lawyer visits Asher at his apartment. She forces him to watch video of Bonnie as a child being molested by her father, which reduces him to tears. It remains unclear what Asher plans to do as the season moves forward, but it seems viewers may find out during episode 6.

The Hapstall case was first introduced in episode 1. The adopted brother and sister were accused of having killed their mother and father and the suspected romantic relationship between them was being looked at as the motive. Caleb and Catherine's aunt took the stand to testify against them, telling the court that she heard gun shots on the evening of the murders and saw her niece and nephew in their parents bedroom. The aunt later turns up dead, with her throat slit in her car. Caleb becomes a suspect in that crime, though Annalise is able to scrounge up enough of an alibi to prove he was on a run somewhere else when the crime occurred. During episode 4 she sent Michaela (Aja Naomi King) in to woo Caleb, hoping he would confess to having been romantic with his sister. He catches on and maintains that he and Catherine are not now, nor were they ever, sleeping together. Catherine volunteers to prove that she's a virgin through medical examination and passes with flying colors.

"HTGAWM" airs Thursday at 10 p.m. EDT on ABC.
