There are just five episodes left to go in The Flash’s final season, and while the series will take a few weeks off after airing this week’s episode, titled “Partners in Time,” the one after that is set to be an especially big deal. “It’s My Party and I’ll Die If I Want To” is bringing back some familiar Arrowverse faces, including Stephen Smell’s Oliver Queen, a.k.a. Green Arrow, who hasn’t been seen on the small screen since Arrow concluded in 2020. Now we finally know why Oliver will be brought back into play for this episode of The Flash.
The basic premise for “It’s My Party and I’ll Die If I Want To” has been established thanks to the trailer shared by TVLine. A surprise birthday party is held for Grant Gustin’s Barry Allen, and among those in attendance are David Ramsey’s John Diggle and Keiynan Lonsdale’s Wally West, the latter of whom hasn’t appeared on The Flash since Season 6. Diggle gives Barry Oliver Queen’s bow as a present, but the party comes quickly crashing to a halt afterwards when the attendees start falling unconscious.
