Taking Flight: Supergirl Episode 310, "Legion of Super-Heroes"

Supergirl has been beaten. Reign has proven superior.

At least for now.

The Maid of Might was indeed down, but she's not out; just comatose. Fortunately, she has some friends at the DEO to help her out -- time travelers from a thousand years in the future: the Legion of Super-Heroes. And while there are a "legion" of them, we only get to meet three of them: Imra Ardeen aka Saturn Girl, Querl Dox aka Brainiac-5, and Mon-El, aka Supergirl's ex-boyfriend Mon-El. They've put her in a healing tank while Brainiac-5 projects his consciousness inside her to assess brain damage by talking with Kara inside the "mind apartment" (Sherlock would be disappointed) she's built to protect herself.

Meanwhile, Reign has a free pass to begin ridding the world of its sinners, among whom she counts those who look the other way and let things happen. It's up to the rest of the DEO to enact a plan created to take down Superman (whom they call Clark; secret identities really don't exist in the CW world), using what little kryptonite they have left. Martian Manhunter takes point, but the Legion is reluctant to join him. They have to survive into the 31st century if they're to complete their own mission.

Unfortunately for the team, the kryptonite -- which affected Supergirl -- doesn't have quite the punch on Reign, and she escapes. The new plan is to inject the kryptonite directly into her system, which would require someone strong enough to plunge the needle in. (This logic bypasses the step of actually having a needle strong enough to puncture invulnerable Kryptonian skin.)

Kara is ready to wake up from her coma, but she's unable to open the door of her mind apartment. She's not afraid, she's sure of that. But there's something in her subconscious that won't let her out until she sees it. Brainiac 5 tries to walk her through things while simultaneously helping the Legion confront Reign. Ultimately, she realizes this isn't a Supergirl problem but a Kara Danvers problem, and she just needs to be able to "see" the thing that will help her open her door.

On a lighter note, Lena Luthor wonders where Kara has disappeared to, feeling a need to talk to her since she and James Olsen shared a kiss. Her family is notorious liars, and she doesn't want to follow that trail with Kara, since Kara and James were once a thing. It's up to the Martian Manhunter to humiliate himself by impersonating Kara to keep Lena off the scent.

"Legion of Super-Heroes" is a fun episode, and I'm sure fans were excited to see at least a representation of the 30th century team. Although it seems that Mon-El not only brought forward the notion that Bon Jovi is a philospher, but also that Bryan Singer is the go-to fashion expert for superhero attire; they look like they're all wearing leftover garb from the original X-MEN movie. I was hoping we were finally okay with colorful costumes for our super characters in CW Land.

Melissa Benoist continues to shine as a down-to-Earth Supergirl, and she is also one of this year's nominees for our Critical Blast Best Actress in a Series (you can vote for her and others here until the end of January 2018). Chris Wood's Mon-El is a thousand years wiser and more composed than we saw him originally, and Amy Jackson's Imra Ardeen was appropriately alien if woefully underutilized. The real standout of the team was Jesse Rath as Brainiac-5, who was less condescending and aloof than his comic book counterpart, and more of the socially awkward nerd with compensation issues.
