‘Supergirl’ Spoilers: What To Expect From Kara’s Encounter With The Black Mercy, Plus ‘The Flash’ Crossover Episode Title

Yes, the big news out right now surrounds the upcoming Supergirl/The Flash crossover, but that’s not airing until Monday, March 28 on CBS. However, the next Supergirl episode is also one to look forward to, as it will see Kara back on Krypton – thanks to her run-in at the end of the last episode.

The last Supergirl episode saw Kara dealing with Maxwell Lord’s Bizarro creation, and while by the end they had managed to neutralize Bizarro and lock Maxwell Lord up at the DEO, Kara had also broken things off with Adam, Cat’s son, before anything really started and came home to a not so nice surprise. As she flew into her apartment, she failed to see something scurrying around – until she noticed something out of place on her coffee table moments before she was attacked by a mysterious plant of some sort.

That plant is the Black Mercy, which is how Kara is going to find herself back on Krypton, as has been teased for a while now, in the next Supergirl episode, “For the Girl Who Has Everything.” This is also how the series is bringing Superman in for this episode – as a boy, as seen in photos from the hour like the one below. Kal-E is a boy, not a baby, because, as executive producer Andrew Kreisberg has explained, via Entertainment Weekly, this is a fantasy where she got to grow up on Krypton.

The promo for “For the Girl Who Has Everything” shows Kara on a table with the plant attached to her, Alex and Hank at her side. Will they be able to save her?

It’s a “telepathic parasite,” Astra explains to Alex. “It has her trapped in her perfect fantasy.”

As for what’s going on in Kara’s “perfect fantasy,” she realizes she’s on Krypton, sees her parents, and realizes it’s not real.

Not only does the promo show that Kara realizes that this fantasy of Krypton not being destroyed and her with her parents isn’t real, but David Harewood has also already teased for TV Guide what that means for her fighting the effects of the Black Mercy.

“She’s basically, in a sense, tricked into believing that everything is hunky-dory, even though her mom and dad are still very much dead. She makes a decision to come out of that, to leave that, because she knows it’s not real, even though it’s very seductive. She knows that she doesn’t really belong there.”

That is a tough decision for someone to make, especially since coming out of that fantasy means returning to a place where her parents – and her planet – are gone, but according to Harewood, that’s why she’s “stronger” for it.

“It would be easy to stay in a Utopian existence,” he said.

Furthermore, this is even more tragic because it’s coming at a point where, as seen recently on Supergirl, things aren’t going so well for her, according to Kreisberg.

“Because it’s coming at a time where she’s feeling so low about her life on Earth, it becomes that much more potent. … She’s actually getting back everything that was taken away from her and the only way out of it is to reject it. Imagine how horrible that’s going to be.”

So, in two words: Poor Kara. It’s going to be a tough Supergirl episode for her.

As has already been announced, there is the upcoming Supergirl crossover with The Flash to also look forward to next month on CBS. Thanks to a photo Grant Gustin tweeted of the cover page of the script, along with the caption, “Really really. Flash is about to meet Supergirl. @melissabenoist,” that episode now has a title, “Worlds Finest,” which may hint at how this crossover is possible. (Remember, multiple Earths have been established on The Flash in Season 2.)

Really really. Flash is about to meet Supergirl. @melissabenoist
