Kate & Toby head for divorce on This Is Us, school's out on Abbott

On today's What to Watch: It's the end of the school year — and the first season — of ABC's breakout comedy Abbott Elementary, where the teachers round up their students for a trip to the Philadelphia Zoo, and star Quinta Brunson teases the action. The case comes to a close on The Thing About Pam, which wraps up its limited series run and murderer Pam Hupp trying to cover her tracks; and on This Is Us, Kate and Toby's marriage hits the point of no return. Will Poulter, who stars in the new series Why Didn't They Ask Evans?, tells us what he's watching. Plus, entertainment headlines — including casting news about the new Percy Jackson, Christopher Lloyd and Rachel Leigh Cook's Spirit Halloween movie, and Justin Bartha's return to the world of National Treasure — and trivia.
