'Supergirl' Star Chyler Leigh Opens Up About #Sanvers Breakup

It was a sad night on “Supergirl,” as Alex Danvers (Chyler Leigh) and Maggie Sawyer (Floriana Lima) called it quits.

The couple, shipped as #Sanvers, was planning their wedding when they realized they wanted different things in life. Alex hoped to be a mom one day, while Maggie did not see herself with children.

ExtraTV.com was on the Vancouver set of “Supergirl,” where Leigh and co-star Melissa Benoist, who plays her sister Kara (and also Supergirl), weighed in on the breakup and the aftermath.

Chyler told reporters, “It's a heavy episode. I mean, there's no way around that, and just say what it is. It is a breakup. And honestly, in a lot of ways, it felt like a genuine breakup. I love Floriana to pieces. She's amazing.”

Leigh revealed that director Kevin Smith made sure to do a separate table read, and opted to film all the scenes in one day. She explained they “wanted to make sure that the words were right… the intention was right and the heart behind it was right.”

As far as the reason for going their separate ways, Leigh said, “There are certain things that you're either always going to want or you're never going to want. In this case with kids, that's a pretty big deal.”

The split was amicable, and Chyler said, “Alex would never wish anything but the absolute best for Maggie and vice versa.” She even gave fans a tiny bit of hope they could reconcile one day, “It's not like an absolute closure because no one ever knows exactly what's going to happen.”

Next week, fans will see the aftermath of the split when Alex and Kara visit their mom Eliza in Midvale. Kara, of course, is still coping with sending away her boyfriend Mon-El last season.

Chyler said, “Ice cream, pizza and the couch scenes are my favorites,” adding, “It's a really, really cool flashback episode where you see kind of the initial dynamic between Kara and Alex and how that was really difficult for them in the beginning and sort of what the catalyst was for the turn in their relationship.”

Benoist also touched on next week's episode, saying, “I know when I've gone through hard breaks and need support, my mother is the first person I want to see. I loved the idea when the writers said, 'Oh, we're going to do this episode in Midvale. I thought it was brilliant and I think it's a really touching story of sisterhood. You get to see a lot of history between Alex and Kara that we've only ever alluded to.”

Melissa said fans will see how “unbreakable their bond is.”
