Supergirl and Saturn Girl Versus Pestilence, Fred Andrews versus Hermione Lodge, and The Return of Tommy Merlyn Coming The Week of April 30

The CW has released the official primetime listings for the week of April 30, 2018, and they include some big moments for Supergirl, Riverdale, and Arrow.

The Maid of Might will team up with Saturn Girl of the Legion of Super-Heroes to stop Pestilence, the third Worldkiller.

The Flash brings Gypsy back and sets up a state-of-the-union kind of conversation between her and Vibe.

Riverdale’s mayoral race heats up as Fred and Hermione prepare for a debate.

Arrow brings back fan-favorite actor Colin Donnell for the first time since “Crisis on Earth-X,” but this time he is (we assume) not a Nazi from an alternate Earth.

iZombie‘s title on April 30 is “Mac-Liv-Moore,” but that is all they have yet revealed about the episode.
