‘Big Little Lies’ episode 3 preview trailer: Mary Louise goes to the cops, but will she turn on Celeste? [WATCH]

In HBO’s spoiler-filled preview trailer for the upcoming episodes of “Big Little Lies” (watch above), your ears will no doubt perk up by what Mary Louise (Meryl Streep) hisses in the final moment: “You don’t believe my son just slipped, do you?” She’s sitting across from Detective Quinlan (Merrin Dungey) at the police station, making good on her word in last week’s episode to go to the cops after discovering that Celeste (Nicole Kidman) learned of Perry’s (Alexander Skarsgard) affair on the very day that he died. Hmm, is she really going to turn on her own daughter-in-law?

Episode 3 of Season 2 airs Sunday, June 23 and it’s once again directed by Andrea Arnold and written by David E. Kelley (based on a story by Kelley and book author Liane Moriarty). Titled “The End of the World,” this hour will deal with the aftermath of Madeline’s (Reese Witherspoon) affair being exposed to Ed (Adam Scott). “There aren’t a lot of happy endings for a lot of people,” Madeline says to a crowd at at a function, no doubt feeling guilty about her tryst from the previous year.

Also in Sunday’s episode, get ready for more of Bonnie (Zoe Kravitz) spiraling out of control as she’s seen walking into the ocean waves, a recurring theme of the series. Celeste tells Madeline and Jane (Shailene Woodley), “If I could do it again, I wouldn’t lie,” a key reference to the fact that they’re all protecting Bonnie for being the one who actually pushed Perry to his death.

But it’s Mary Louise who steals the trailer, declaring in ominous voice-over, “People can move on after a tragedy, just not together. Sometimes.” There’s also a quick moment of Mary Louise watching Jane and Ziggy (Iain Armitage) from afar, having recently found out that she’s the child’s paternal grandmother. How might Jane react to meeting with the mother of the man who sexually assaulted her all those years ago?
