Supergirl is humbled by her latest foe, and James butts heads with Cat at work.

You dont just put on a cape and join the Justice League and start saving the world.

You have to build up to that.

The shows infectious joy returns right at the start of the episode.

We open out in the desert, where the DEO is testing Karas skills.

Shes zipping through the sky and dodging missiles like its no problem at all.

Yeah, Kara definitely isnt going to agree to that.

A Fort Rozz escapee attacks some workers at chemical plant, which leads to the DEO being called in.

I really hope the show flashes back to her first few days on Earth.

Hank is concerned that Kara doesnt know how not to be killed.

So, Alex takes Kara into a Kryptonite-lined room for some hand-to-hand combat.

Its actually a great-looking scene, and I love how the camera circles around the women.

On an equal playing field because of the Kryptonite, Alex beats Kara and severely bruises Karas confidence.

Then, Kara returns to work and sees Cats latest headline, Supergirl: Failure to Launch.

Cat thinks Supergirl need to calm down and start small.

Meanwhile, Big Bad Aunt Astra and her minions corner the Hellgrammite.

Astra plans on using the Hellgrammite as bait to lure her niece out.

NEXT: What does the S mean?

Its zippy and fun until Agent Well-Intentioned Buzzkill, a.k.a.

Alex, shows up and reprimands Kara for telling Winn and James about her secret.

Like all traps on TV, this goes awry.

Several DEO agents are killed and injured, and the Hellgrammite kidnaps Alex.

After overhearing the conversation, Kara tells James shell do the interview, but he turns her down.

He came to National City to become more than Supermans pal, to become his own man.

Kara then proceeds to shatter his outdated view of masculinity.

This scene also clarifies Karas approach to being a superhero.

By the way, you should be readingAction Comics.

Unfortunately, Kara and James heart-to-heart is interrupted by Hank, who calls to tell her about Alexs abduction.

Hank shows up, and Astra tries to kill him.

But he stabs her with a Kryptonite blade, and she runs away.

Karas first request is for hug, but the hologram isnt programmed to do that.

So, she asks for the next best thing: everything it knows about Astra.

Meanwhile, Alex thanks Hank for setting the room up.

As he walks away, his eyes glow red.

Clearly, hes hiding some kind of secret, too!

(This is another homage toSuperman lore.)
