Some big changes happen in this week's episode of Supergirl. Are they good changes? That's debatable. Here's what happened:
Supergirl 3x21 "Not In Kansas"
At the end of the last episode, Reign broke free from her chains just as Kara and Mon-El returned from Argo with the rock that Lena can use to save Sam. Right away, Lena gets to work as Kara and Mon-El hold back Reign with a little combat. Just as the two of them manage to get Reign in a bit of a hold, Lena runs over and injects Reign with something, and a moment later, Sam emerges as Reign fades away. Sam is taken to rest and later Alex brings Ruby over. All is well!
So well, in fact, that Kara decides to move to Argo to be with her mom. As she tells Alex in a wonderful sister scene, she's always felt incomplete on Earth, so she wants to go live her true life in space. Alex is sad to see her sister go but knows it's what she wants. So Kara bids a sweet goodbye to the DEO, who throws her a cute party (as does CatCo, and are you seriously telling me that Lena still can't connect the dots when Kara and Supergirl are leaving at the same time?). Joining her in the move to Argo is Mon-El, because he has nothing better to do. On Argo, Alura is so pleased to have Kara back, and Kara also runs into an old friend named Thara. But even with things seemly being good, Kara still feels uneasy, and this is only furthered when she starts seeing a hooded figure around. After another sighting, Kara chases after the figure and yanks off the hood to reveal a random lady who insists she's done nothing wrong. Everyone thinks Kara's paranoia is weird. But later on, when Kara and Mon-El are having A Moment, they're attacked by a robot and they find that it was sent by the lady, who can't play innocent this time. The lady calmly admits that she works for Selena, the shady council member. Kara and Alura and Thara (who is a Peace Officer) are shocked. What, none of you noticed how sketchy Selena was?
Meanwhile, back on Earth, James has taken over as the city's main hero, and with Winn in his ear, he saves a police officer from being shot by some gunman. But later Winn examines the dents in James' shield and finds out that the bullets came from an assault rifle that only cops and the FBI and the DEO should own. So James and J'onn go meet with the gun manufacturer, who agrees to work with them to figure out who the gunman is, but is also a pro-gun man who believes every American should be armed. Yeah, this rich white dude said that to two black men. Anyway, they do end up figuring out who the gunman is and that his next target is his old workplace. The DEO heads there, and J'onn is the one to find him first. He manages to talk him down and take the gun. Between that and the earlier conversation with the gun manufacturer, J'onn has done some thinking and he gathers everyone at the DEO to announce that he's phasing out lethal weapons. Some people aren't thrilled with this, but I'm sure Winn will be able to develop some type of other gun for them soon. What they need is Fitz's night-night gun from Agents Of SHIELD.
Last scenes of the episode are Alex pulling up a National City adoption website (give her a new love interest, you cowards!), Sam suddenly dropping a glass while hanging out with Ruby, Kara finding out that her ship has been stolen on Argo, and Selena taking the evil fortress key from Coville and raising the fortress.
All in all, a weak episode. The thing about Kara going back to Argo was that we just knew it wouldn't be for more than an episode or two at most, and Argo doesn't even have a lot to offer. So the whole big goodbye was a waste of time. And while I give kudos to the show for addressing gun control in a non-preachy way, even that whole plotline was boring. We've got two episodes left, and the show is not doing a great job getting us hyped. What did you think of the episode?
