His real name is Querl Dox, but his fellow Legion of Super-Heroes call him Brainy.

(Gotta love that this is still an expression in the 31st century!)

He explains that shes in a manifestation of her happy place while 31st-century technology heals her body.

Hey, remember that Ruby cliffhanger?

She and her mom are engaged in a Nerf gun war.

Jonn suggests they invoke the Sundown Protocol, designed to take out Superman if he goes rogue.

In her mind palace, Karas thrilled when Brainy tells her that theyre ready to wake her up.

Since her body and brain are fine, Brainy suggests that her subconscious may be scared.

Kara strenuously rejects that idea, first punching the door and then eye-lasering it.

But he warns that the longer Kara stays asleep, the less likely she is to wake up.

Part of it involves manufacturing new Sundown Protocol weapons, which means Jonn has an hour to kill.

Okay, this scene was funny, but…come on.

Unfortunately, their best bet is still asleep.

She finds a photo of her catStreaky, who suddenly appears on a chair.

Kara settles him onto her lap, explaining that she found him right after she came to Earth.

Supercat for the win!

Their job is to help people, and these people need help.

(To the person choosing music forSupergirlthis season: Marry me.)

In Karas mind palace, she realizes Brainys multitasking, talking to her and engaging in a battle.

A little tiny baby battle, he assures her.

Karas had enough and tells him to focus on the fight.

Before he leaves, he reminds her that Kara Danvers is Alexs favorite person.

She wakes up in the real world and immediately rushes into battle.

(Also, was she wearing her super-suit the whole time she was asleep?

Shes fantastic in battle, in other words.

Seriously, these private declarations havegotto make it harder for all three of them to work together, no?

Afterward, Karas excited to meet Brainy in the real world.

Hey, its you!

Yep, he augmented his height in her mind palace to make himself seem more stable and trustworthy.

This worried me because Brainiac 5 isSupergirls main love interest in the comics, and Im shallow.

At CatCo, Lena tells James that shes used to people reflexively hating her because of her family name.

Hes pleased that she figured out that hes not one of them, and they kiss some more.

It still hurts, but Ill be stronger for it, whatever happens.

They toast to avoiding comas in the future.

Finally, Reigns in her Fortress, waiting for the Kryptonite to wear off.

Stronger together, Coville says, translating the words that Reigns dark mentor hisses.
