Here’s what’s happening in the world of television for Monday, May 20. All times are Eastern.
DC’s Legends Of Tomorrow (The CW, 8 p.m., fourth-season finale): At last we have arrived at NeRay’s (that’s Ray possessed by demonic spirit Neron) end game—make the public afraid of magical creatures and scare them into downloading his app so they can sign away their souls. Thankfully, the Legends have a plan to unite the world’s magical creatures and save Ray’s soul in the process: build a magical amusement park! Plus, they raid the Arrowverse costume closet, all on tonight’s season finale.
Fleabag (Amazon, ongoing): Episode four
