What to Watch podcast: It's guest stars galore on Grey's Anatomy 's season 18 finale, marking its 400th episode

At the end of its 18th season, Grey's Anatomy celebrates its 400th episode, where Meredith takes a big risk on a patient. The Flight Attendant lands its second season, with Kaley Cuoco's Cassie spiraling yet again after Dot shares some classified information with her. And the survival series Alone kicks off its ninth season, with 10 contestants left in the wilderness with ten items of their choosing — and only one will win $500,000.

Comic Guy Branum tells us what he's watching. Plus, entertainment headlines — including the development of a new live-action Speed Racer series from J.J. Abrams, Abbott Elementary star/creator Quinta Brunson's reaction to fans asking for a school shooting episode, and reality star Josh Duggar's prison sentencing — and trivia.
