Here’s what’s up in the world of TV for Thursday, April 20. All times are Eastern.

Top pick

Scandal (ABC, 9 p.m.): As Ashley Ray-Harris pointed out, Scandal’s 100th episode reminded viewers just how good they have it, even when the show’s at its worst. The truth is, the alternative to the high-strung drama would be too ordinary for us.

Regular coverage

Trial & Error wrapped earlier this week, and as for Grey’s Anatomy and Riverdale:

Wild card

Supermansion (Crackle, 3 a.m.): Crackle’s star-studded stop-motion comedy wraps its second season with an earthbound battle between intergalactic opponents. The Subtopian army wants to take over our planet, so the League Of Freedom forms an unholy alliance with the Injustice Club to thwart them. But the question remains: Can Rex (Bryan Cranston), Lex (Jillian Bell), and Dr. Devizo (Chris Pine) set their bullshit aside long enough to fend off an alien invasion?
