Alex (Chyler Leigh) finds herself in serious trouble in Season 2, episode 19 of “Supergirl,” and despite Kara (Melissa Benoist) and Maggie’s (Floriana Lima) differences in dealing with things, the two must work together to save the woman they both care about.

“Episode 19 is a very big episode for [Alex and Maggie] just because it comes to dire circumstances, where it’s a situation of a rescue,” Leigh revealed to Entertainment Weekly on the news outlet’s SiriusXM radio show, “Superhero Insider.”

“It causes Kara and Maggie to have to rely on each other to figure out what happened to Alex,” Leigh added. “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 aliens. It’s this really great example of how deep all of the relationships are.”

Although Leigh said that the episode is going to put Maggie and Alex’s relationship to the test once again, Leigh previously implied that the two might be reaching a new milestone in their relationship before Season 2 ends.

“They have a lot to grow together,” Leigh said of the couple in an interview with Entertainment Weekly last month. “But they are [also] realizing how serious they are about each other, so I think there’s some things coming up that would take it maybe to the next level.”

Although that could mean one of them might be popping the big question soon, Leigh’s teaser could also suggest other things, like Maggie moving into Alex’s place or Maggie finally introducing Alex to her family.

“Supergirl” returns from its month-long hiatus with Season 2, episode 18 on Monday, April 24 at 8 p.m. EDT on The CW. Season 2, episode 19 airs the following Monday, May 1 in the same time slot.
