Entertainment Weekly is reporting that Alex and Maggie are in for a big event in episode 19 of season 2! In a recent interview with Chyler Leigh on Superhero Insider, Chyler spoke to the hazards that may face Kara and Maggie in the future! The two will have to work together to help find/save Alex! We have more on this in the spoilers section which we will try and leave out from this article but here's what Chyler had to say:
Episode 19 is a very big episode for the both of them just because it comes to dire circumstances, where it’s a situation of a rescue. It causes Kara and Maggie to have to rely on each other to figure out what happened to Alex… You have to see how they work together, and you have to see how they’re both fighting for the person that they love, that they care about, and how that can take a toll if you have differing opinions, different ways that you kill[/influence] aliens. It’s this really great example of how deep all of the relationships are, but it really does put Maggie and Alex to the test in a very great way, but it’s rather dire.
We do want to be clear here though, EW has said before that an episode is "Sanvers-centric" but fans felt let down by that description. So take this news not that the episode is Sanvers-centric but will have big events for Sanvers.
