Hey, Super-fans! Long time, no recap! But we’re back, and just in time to watch some of our favorite characters make tough choices on behalf of the people they love tonight.

First, let’s catch up with Lena and Sam. Lena’s been running tests while Sam’s in a medically-induced coma, and she’s got proof that Sam’s cells mutate during her blackouts, turning her into Reign.

Sam strenuously (and understandably) denies this. Bless Lena’s evidence-loving heart, she offers photos of Reign’s appearances that match Sam’s blackouts, but Sam still refuses to believe her (even though that’s clearly herself wearing dark lippy and a Reign mask).

Lena refuses to let Sam leave her L Corp cell, for her own sake and for Ruby’s, which causes Sam to lash out: Ask an oncologist for a diagnosis, and they say it’s cancer. Ask a Luthor, and they’ll tell you you’re a supervillain. Ouch.

Lena stays ice cold and starts needling Sam, asking how she can possibly forget attacking Morgan Edge, punching Supergirl, and ripping those criminals apart, all while living with her vulnerable daughter. “You’re not a mother, you’re a monster,” Lena announces.

The tough love does its job and triggers a Reign episode that transports Sam to a dark forest where you’d definitely never want to picnic.

Sam wakes up to find footage of her Reign transformation playing in her trashed cell, and when she sinks to the floor weeping, Lena deactivates the cell and steps inside to comfort her friend. “All those people,” Sam sobs, and Lena assures her that they’ll find a fix thanks to the Reign DNA she collected while Sam was out.

While Lena’s been working with Sam, she’s been neglecting James, but he proves himself to be an exemplary boyfriend for someone with a secret, telling her she doesn’t need to confide in him while offering advice, a listening ear, and take-out dinner.

Having a little more fun at the beginning of this episode are Kara and Co. as they gather to play charades. (Myr’nn cheats by both shapeshifting and using his mind-reading powers, but c’mon, who among us wouldn’t, if given the chance?)

Then, as the kids say, he spills the tea on his son, telling the group that J’onn used to switch the pieces on his Ok-Rock-Tock board and blame his imaginary friend, a fifth-dimensional imp named Zook.

An SOS interrupts the night, and everyone heads to the alien bar, where a Kalanorian went berserk and started tearing the place apart. She even tosses Supergirl into the arcade game where Kara held the high score. Rude!

The DEO are surprised by the Kalanorian’s unusual behavior, which J’onn chalks up to her psychic abilities and Mercury rising. (The sisters Danver are amused that the explanation is astrology, to which J’onn replies, “More like complex luminal and gravatic shifts that determine Kalanorian brain function, but sure. Astrology.”

J’onn may joke, but but he’s also worried about his father, who’s struggling with za-alet, the decay of memory. Without informing anyone, J’onn decides to bring Myr’nn to the DEO to perform the Ta’ar-Kar’riq ritual, which moves information from the decaying parts of his mind to the healthy parts. Yep, I’m sure nothing will go wrong with that!

Elsewhere in the DEO, Mon-El explains that the still-unidentified third Wordkiller, Pestilence, should be the easiest to see coming because it presents as a plague, bringing illness and death in its wake.

To prepare, Kara and Mon-El review some Brainy-provided 3D imagery of past Reign fights and decide to do some Legionnaire-style training. Specifically, Mon-El cape-splains that both of their uniforms cloaks are made of Kryptonian smart cloth, which he mastered using as a weapon during his time in the future.

Kitted out in his old Legion suit, Mon-El shows Kara how to wrap her cape around an object and toss it, but she struggles. Hard. And the more she struggles, the more frustrated she gets until she’s yelling about all those times Mon-El tanked his training, but he was generally hungover at the time. (They may not be in sync, but you’ve gotta love the coordinating reds and blues of their super-suits.)

Elsewhere, Winn and DEO tech guy Demos also get shouty, and when Demos calls Winn an “egotistical little son of a serial killer,” things get physical. Even the locked-up alien baddies are as agitated as the good guys, including Alex, who angrily breaks up the nerd fight. When Kara storms in to stop Alex, J’onn throws metaphorical cold water over everybody with a psychic barrier. In the middle of it all, Myr’nn fervently chants.

J’onn finally confesses that Myr’nn’s anger and fear as he employs Ta’ar-Kar’riq is causing a powerful psychic bleed that’s amping up the aggression of everyone in the vicinity. J’onn thought he could shield the DEO and keep them all safe, and now he fears the option left is using dampening technology on his father.

But he doesn’t want to lose the father he just got back, and he’d rather face a football stadium full of Worldkillers than do the one thing that centuries of imprisonment by White Martians never did: strip his father of his independence and dignity. (Next: Kara gets some things off her chest)

Kara tells J’onn that her uncle Jor-El used to say, “The son becomes the father and the father the son,” which spurs J’onn to take Myr’nn into a locked room to break the news that his psychic angst has affected everyone. This agitates the gentle man, who insists he’d never hurt anyone. Then he lashes out, shouting, “Don’t you dare tell your father what he is or isn’t able to do,” causing J’onn to wince in psychic pain.

Unfortunately, Myr’nn pumps all of his negative energy out just as Mon-El interrupts Kara’s cape-kata to ask why she punched him during their last session. She blames it on the Martian angst only and absolutely not on any deeper underlying feelings, then invites him to resume their training.

But before long, she’s unloading on Mon-El, venting about his former bad behavior — for which she apologized to him — and expressing her disbelief that she fell in love with an unrepentant jackass who was thoughtless and disrespectful toward her then and now shows up reformed and wanting to reminisce.

Mon-El, whose Legion ring shields him from the mental Martian aggression, takes it all in until finally Alex arrives with a psychic dampener for Kara. Winn recalibrated the Psi-stopping technology, which now blocks the Martian psychic bleed and allows Kara to think clearly.

Good thing, because the DEO’s a madhouse by this point. The prisoners have all escaped and are juiced up on anger and fear, plus non-dampener-wearing DEO employees want to fight each other. (This includes Pam from HR, who comes gunning for Winn for reasons that we never learn, alas.)

As the facility devolves into a chaotic brawl, Myr’nn reacts badly to J’onn’s suggestion of a dampening bracelet, which he likens to being back in a cell. He transports himself out of the room, and J’onn follows to plead with his father to trust him.

Mid-fight, Kara finally masters her cape techniques. (Learn by doing, Supergirl! Learn by doing!) She uses it to subdue a few bad guys as Mon-El gives her a rather paternal nod of approval.

Then a White Martian strolls by, causing Myr’nn to panic. As J’onn gives chase, Kara stays with Myr’nn, urging him to accept the changes in his life and make the best of it. Then J’onn returns to repeat Kara’s words about fathers and sons. He touches Myr’nn’s face, and his father allows him to put the inhibitor on. The instant the bracelet circles his wrist, the chaos ends, and the two Martians hug.

As a crew cleans the wreckage of the DEO, Myr’nn gathers everyone to apologize that his fear of losing control hurt them all. And then J’onn apologizes for not protecting them all, but Kara and Alex assure him that it was their privilege to protect him for the night.

Oh, and you thought that was an overload of apologies? Just wait. Mon-El finds Kara working through her cape-kata alone, and she explains that after he left, she had a tendency to romanticize their imperfect relationship. But airing all of her grievances was a huge weight off of her shoulders. “I’m just really sorry that it took a Martian attack to make it come out,” she says.

Mon-El then acknowledges his past jerky ways and apologizes, and then Kara apologizes back and then, mercifully, they agree to stop apologizing to one another and go be heroes. But their buoyant side-by-side flight is interrupted when birds start dropping dead from the sky.

Uh oh. Looks like Pestilence is in town.

Snaps of the cape

  • Mon-El critics: Do you feel seen? Because it sure sounded like the writers heard your feedback and worked it into Kara’s reactions tonight. Mon-El lovers: Was this the fresh start for the duo that you’ve been hoping for? Mon-El beard-watchers: WHY HASN’T HE SHAVED YET???
  • At this point, Supergirl’s thiiiis close to having characters say, “Oh, Brainy? He ran out to pick up a carton of milk.” All that face paint ain’t cheap, apparently. But he and Imra checking out a river of blood seems legit, as far as excuses go.
  • Myr’nn plays Ok-Rock-Tock because it centers him, connects him to his ancestors, and eases his mind. Cool. Cool, cool, cool. On Earth, we call that Candy Crush.
  • Highlight of the episode: Kara carefully unbuttoning her blouse mid-Supergirl transformation and telling the room, “What? I like this shirt!” Oh, how I missed this wholesome, adorable crew during the hiatus!
  • So do we prefer “Martian Man Father” or “Martian Dad Hunter” for Myr’nn?
