'How to Get Away With Murder' season 3 episode 5 spoilers: It's all about Frank… and Laurel

Three people have been confirmed safe from the devastating fire at Annalise's (Viola Davis) house, and one of them was a pregnant Laurel (Karla Souza). But how long can she last with Annalise's not-so-innocent accomplices sniffing at her heels?

According to the press release posted by Spoiler TV for the upcoming episode of "How to Get Away with Murder," more clues are to be expected now that the narrative is inching closer to this season's big reveal. A shocking discovery may just change the way fans of the hit legal mystery drama view the fire at Annalise's place.

The mystery of the killer flyers would also be tackled with an unexpected twist. A look into Frank's (Charlie Weber) troubled past may shed light on the motivation that drove him to kill Bonnie's (Liza Weil) abusive father, Bob (Ronald F. Hoiseck), in last week's episode.

Additionally, Bonnie and Laurel now share a secret that they could not tell Annalise about. How long would it take for the astute defense attorney to catch up on their lies about Frank's whereabouts?

Another mystery that needs to be answered is the Laurel's pregnancy. In an interview with Variety, actor Matt McGorry was asked if it was possible for either Frank or Wes to have fathered Lauerl's baby. McGorry said that anything was possible and that the truth would eventually be revealed as "How to Get Away with Murder" season 3 progressed.

"Part of what makes the writing so good and interesting is that you never really can guess what's going to happen," McGorry added.

The preview for this week's episode titled "It's About Frank" also showed Grammy-award winning singer Mary J. Blige in a guest starring role as Annalise's hair stylist. Whether this will be a one-time or recurring character remains to be seen.

"How to Get Away with Murder" season 3 episode 5 titled," It's About Frank," will air on Thursday, Oct. 20, at 10 p.m. EDT on ABC.
