Finally, a character from one of The CW’s DC Comics TV shows has officially come out: Alex (Chyler Leigh) from Supergirl!

Over the past few episodes, viewers couldn’t deny the crackling chemistry between Kara’s (Melissa Benoist) adoptive sister and her new detective friend Maggie Sawyer (Floriana Lima). They’ve been working together to solve cases, hanging out drinking at bars in their downtime, even finishing each other’s sentences. And when Alex saw Maggie kissing her girlfriend, she definitely looked jealous. So when Maggie’s girlfriend dumped her, Alex tried to cheer her up by asking her out for drinks in “Crossfire.” When Maggie responded that she wasn’t ready to date again yet, Alex was shocked to learn that Maggie thought she was gay, and she denied that, claiming she only asked Maggie out as a friend.

But by the end of the episode, Alex had done some serious soul searching and came out to Maggie in a heart-to-heart. She confessed that the reason she’d always been so bad at dating all her life was because she never wanted to be intimate with the men she was with, and now she realized it was because she didn’t want to be with men — she wanted to be with Maggie. And according to Benoist, Kara is going to be there for her older sister while she goes on this new journey of self-discovery in her coming out process.

“I think that really season one serviced the purpose to get Kara on solid ground herself, so now that Alex is kind of going off on her own path and learning something about herself, I think Kara will be there with just an open mind and an open heart,” Benoist told us on set in Vancouver. “You know, those two are inseparable. Their bond is unbreakable. So whatever happens, Kara’s going to be there no matter what.”

Another character who is going to find themselves on a journey of self-discovery is Mon-El (Chris Wood). After spending “Crossfire” trying to fit into Kara’s idea of what an alien should do to blend into Earth society, both he and Kara realized he needed to find his own place in the world. While the glasses and button-up shirts and job at CatCo worked for Kara, it didn’t exactly fit him, and she needed to let him figure out what did work for him.

“I think that obviously was a big lesson for her to learn, and she kind of didn’t realize she was living vicariously through him to fulfill that process she made to her parents to protect Kal-El [Tyler Hoechlin],” Benoist says. “So I think from that point forward, it’s really Kara learning and trying to just get to know and be tolerant of Mon-El and how different he is from her. So when that settles, I think it gives them a much broader profile to grow from as friends, as allies, even though they come from these warring planets.”

Wood was excited to get to explore who Mon-El is as a person now that he isn’t being molded by Kara or hunted by the DEO.

“I think the first episode especially once I wake up, that’s really a scared fight-to-stay-alive which isn’t really him,” Wood shared with us on set. “It’s sort of this contentious ready-to-fight side. And by [episode] 5 he’s relaxed enough and going to work and things are exciting like Twizzlers and he’s kind of riding high on all the newness.”

He continues, “I think Mon-El’s first thing he wants to do is find a job that makes him excited. I don’t know if he has it in him to seek something that involves working very hard because he likes fun and partying. So he has to find something that fits a little niche. And Kara also has to approve obviously, so there’s a bit of an exploration going on for him after that.”

While Mon-El already manipulated Winn (Jeremy Jordan) into going out and getting drunk with him, expect him to be working closely with Kara only from now on.

“He’s still an outsider,” Wood admitted. “These guys all know each other, they work together, they’re related by blood and by family, and they all sort of have this history together and he’s still on the outside. I think that sits with him kind of in a difficult place and it takes him a little while to adjust to that and finding his role in this group other than Kara who he can talk to and connect to and sort of feel like himself.”

And as he and Kara get closer, their dynamic will evolve, leading to some personal growth in Kara as well.

“The mentor-mentee relationship is how she first opens up to not just hating him because he’s Daxam,” Wood said. “And I think from there it’s nice that whatever their differences are, they sort of fade away and they find their similarities that they can cling to and they become friends. But she’s definitely still someone he looks to as an example because she’s got it all figured out. She has the same powers which are more honed and developed. And she also has this great sense of right and wrong which Mon-El doesn’t really understand. He didn’t grow up with that. He wasn’t taught that exact moral compass, so that’s his journey of finding his place.”

While Kara believes that Mon-El’s place is also fighting to save humans, Mon-El might choose to take a different path and not suit up to become a superhero.

“When we see him on the next episode, the focus is more, ‘Let’s get you out in the world and get the normal you first. Let’s get that figured out because that’s easy to screw up. And once we have ‘Mike’ figured out, we can come back and see what part of you will fit into the DEO level, if any,'” Wood says. “He’s never had to think about that before, so he’s coming from a life where he had a job and he did that and now he’s here and someone’s telling him he’s got to figure it out for himself and he’s never really had to do that. I think with time we’ll see him find which part of what Kara does inspires him and try to hold on to that as a common force to hopefully join up with them.”
