Here’s what’s happening in the world of television for Monday, May 13. All times are Eastern.
Arrow (The CW, 9 p.m., seventh season finale): The latter half of Arrow’s seventh season has largely focused on Oliver’s attempt to establish a relationship with his estranged half-sister Emiko. But after she revealed herself to be running the Ninth Circle, threatened the life of a pregnant Felicity, and dropped a building on Team Arrow, it’s safe to say that Ollie is probably done making amends, so fans can expect a heated confrontation between the two Queens in Arrow’s (penultimate) season finale. Tonight also marks Emily Bett Rickard’s final episode as a series regular, in what should be an emotional goodbye. Allison Shoemaker will be on hand to cover all the proceedings.
DC’s Legends Of Tomorrow (The CW, 8 p.m.)
Cherynobl (HBO, 9 p.m.): HBO’s bleak look at the 1986 Cherynobl nuclear disaster continues this week, exploring the fallout of the explosion, and the threats that could devastate the country.
