The CW is the place to be on the small screen when it comes to superhero action, and the network in midseason 2018 will see no fewer than five superhero shows on the airwaves. Unfortunately, the addition of Black Lightning to the superhero lineup has meant that Supergirl lost its place in primetime for a while. A scheduling switcheroo is taking place that will see Legends of Tomorrow moved into Supergirl's regular Monday slot, with The Flash and Black Lightning on Tuesdays and Arrow staying put on Thursdays. Supergirl will return to The CW on Monday, April 16 at 8 p.m. ET.
The April 16 return of Supergirl means that the Girl of Steel will be off the air for more than two months, unless she turns up on Earth-1 for a cameo. Earth-38 has cameoed on The Flash in the past, and it's not out of the question for Kara or one of her pals to turn up on one of The CW's other superhero shows, but we definitely shouldn't count on seeing more of the Supergirl characters except for trailers until April 16. Until then, we can only wait and speculate about what's to come.
The good news is that there's plenty to speculate about during the next two months. Supergirl has spent the majority of Season 3 building the mystery of Reign even as Kara and the D.E.O. try to keep a handle on the regular wild baddies who pop up in National City. Throw in the drama courtesy of Mon-El, the Legion of Super-Heroes, and Alex's emotional upheaval, and kind of a lot has been happening. As of the latest episode, Kara and Co. may be in the most danger they've been in since the show began.
As a Worldkiller, Reign was already arguably Kara's most dangerous foe over the series to date. The Girl of Steel has been outmatched in her showdowns against just the one Worldkiller so far, and the only big win the good guys got over Reign so far took the united efforts of Kara, Martian Manhunter, and the Legion of Super-Heroes. The very bad news is that there are more Worldkillers out there, and Reign managed to get her hands on another: Purity. Although Purity was determined not to be turned into a villainess, Reign hasn't failed at much yet. If Reign turns Purity and recruits the other Worldkillers who are still out there, the good guys of National City might not stand a chance.
The biggest variable at this point is Lena Luthor. At the end of the latest episode, Lena witnessed the flash of red in Sam's eyes as she very nearly transitioned into her Reign personality. Instead of immediately deciding to track down Supergirl and fill the D.E.O. in on the situation, Lena told Sam that she knew what was going on and she would take care of Sam. Lena has been descending further and further into darkness in Season 3; while she still isn't anything approaching a true Supergirl villain, she isn't exactly on the straight and narrow. Lena and Reign could be a very dangerous combination.
