It’s time to face the big boss. In the season-finale promo for Big Little Lies, our heroes — Renata, Madeline, Celeste, Bonnie, and Shailene Woodley’s character — are gearing up to take down the undefeated champ, Mary Louise (Meryl Streep). In her corner, Mary Louise has her masterful way of annihilating defenses and picking at someone’s most vulnerable parts. But in Celeste’s corner, she has the American judicial system on her side, and it’s never given an unfair verdict. Not to mention a quartet of feisty moms who would do anything to protect themselves (well, and Celeste, but mostly themselves). Yes, morale is low (“The Monterey Five, whatever we call ourselves, the lie is the friendship,” Celeste breathes), but it’s nothing a rousing speech by Madeline can’t fix. Hopefully, next week, Mary Louise’s reign of terror will finally end and the judge will slam a soft-serve-ice-cream cone onto her head.
