What to Watch Monday, August 31, 2026: Love Island USA Reunion, American Ninja Warrior Finale & More

Monday is closing out August with reunions, finales and a few familiar favorites. The Love Island USA Season 8 reunion gets our Top Pick tonight as the Islanders reunite after leaving Fiji, while American Ninja Warrior crowns its Season 18 champion and Dancing With the Stars: The Next Pro reaches its first-season finale.

There’s also a new All American, more from The Librarians: The Next Chapter, and plenty of U.S. Open tennis for anyone looking to spend the day on the court.

⭐ The TV Cave Top Pick: Love Island USA Season 8 Reunion

The villa may be closed, but there is apparently still plenty to discuss.

Love Island USA brings the Season 8 cast back together tonight at 9 p.m. ET on Peacock, with Ariana Madix and Andy Cohen hosting the reunion. Winners Trinity Tatum and Bryce Dettloff are among the Islanders returning alongside Aniya Harvey and Carl Schmidt, Melanie Moreno and Sincere Rhea, Kayda Bosse and Zach Georgiou, KC Chandler and Tierra Davis, Kenzie Annis and Dylan Wrona, and plenty of familiar bombshells and Casa Amor faces.

And yes, we have questions. Peacock is promising a look back at the season as the Islanders address what happened inside the villa and what has gone down since they left Fiji. Madix has also teased previously unseen footage that could clear up some of the situations fans have spent the past several weeks debating online.

Considering how much discourse this cast has managed to generate since the finale, something tells us everybody isn't simply showing up to exchange hugs and talk about how much they've grown. We will be seated.
