It's bad enough that Livewire has broken out of prison and attacked the NCPD, but things get even worse when Mon-El puts Supergirl ahead of the citizens of National City.
We are fairly certain Kara would not approve of that. Meanwhile, James is finally ready to come clean to Kara. How will she take it?
On top of all that, M'gann collapses into a coma!
Scroll through the photos for your first look at what sounds like an action-packed installment, and watch Supergirl online if you're behind.

I hate having a nemesis. Clark always makes it look so much fun, like you have a deadly pen pal you see once a year. But having a nemesis is stressful.
Winn: If there's a flaw in your suit, that means the suit is faulty. Which means I have to go fix it. And that already on top of me having to make Mon-El a suit. James: Mon-El? Winn: Oh yeah, didn't you hear? He graduated from superhero kindergarten, so now I have to make him a suit, according to Kara. And that just means more work for me.
