The next morning when Kara wakes up, Lena is still asleep in Alex's bed. Kara briefly wonders whether she should've slept on the couch downstairs rather than in her own bed. She had been so tired, she hadn't even thought about it. She can't imagine Lena being happy to find Kara in the room with her when she wakes up, so Kara quickly gets up and heads downstairs.

She walks into the kitchen and finds Eliza there drinking coffee. The quality of the light pouring in through the windows makes Kara realize it must still be early. Kara takes a deep breath in. It feels good to be home.

"Morning," she says warmly.

"Morning, darling." Eliza is happy to see her daughter looking well rested and much more relaxed than she had the night before. Eliza raises her coffee cup. "You want some?", she asks.

"Oh yes, please."

Kara sits down at the table. She feels Eliza's eyes on her, trying to read her. She knows her foster mother is weighing whether she should push her younger daughter to open up or leave her be for now. Kara hasn't always been great at opening up about difficult things in the past. This morning, however, she feels it would be nice to talk to Eliza.

She decides to plunge right in: "Lena found out I'm Supergirl."

Eliza looks shocked.

"Oh honey. You still hadn't told her?"

Kara shakes her head.

Eliza takes a moment to think.

"Why not? Because of her family?"

"No, it had nothing to do with that."

"So you do trust her?"

"I do. Of course I do. She's my best friend."

Eliza looks puzzled for a moment and then asks, "Why then?"

Kara takes a long moment to think. "I think it was different things," she finally says. "You know how when I first came to earth we decided no one should know I wasn't human. It was probably wise, but it was also really lonely. I had to keep such a huge part of myself hidden from so many people. Then I became Supergirl and I told my closest friends and I felt more like a whole person."

Eliza nods. She remembers the conversations, the worries, the difficult decisions all too well.

"When I told my human friends I have these powers, that I'm from Krypton," Kara continues, "it drew us closer, but it also created a distance. It took away the lies, but it also brought to the fore that I'm very different from them. I can do things they can't and because of that I have responsibilities they don't.

And then with Lena, I was just Kara. None of that distance existed. I loved that about being with her. And I relished that I didn't need any superpowers for this woman who was the smartest and most accomplished person I'd ever met to want to be friends with me. And I thought I'd just wait a little while to tell her. But then I started to understand how difficult trust was for her. How many people close to her had betrayed her. It was so hard for her to open up to people. But she started to open up to me. We got closer and closer. And I loved it and at the same time I felt so torn by it. I wanted to tell her the truth, but I also didn't want to be yet another person to let her down. I didn't want her to have to experience that again. So I waited for the right moment and it just never came."

Kara is silent for a few moments as it hits her again how deeply hurt Lena must have felt these past few weeks.

Feeling Eliza's eyes on her, Kara also realizes that what she's told Eliza isn't the whole truth. She takes a deep breath and adds slowly, "Lena learned how to make kryptonite when we were fighting Reign. I freaked out. It made me feel so vulnerable."

Avoiding Eliza's eyes and looking down at her hands, Kara continues: "I asked James to break into her lab. When she found out, she felt so betrayed."

"Oh Kara."

"When she told Kara she could never trust Supergirl again, i knew I had to tell her. I knew I had to come clean. But I just couldn't do it. I wanted her to still have a friend she could trust. A friend who hadn't betrayed her."

Kara feels herself choke up. "And I didn't want to lose her," she whispers.

Eliza looks at her warmly. "So you never told her."

Kara shakes her head. "I tried to. On the way back from Kaznia I even took off my glasses. I was ready to tell her. But I just couldn't do it. I couldn't tell her."

Tears fall down Kara's cheeks.

"And now it's all ruined. I think I've lost her forever."

"Oh honey." Eliza grabs hold of Kara's hand. "Don't give up on her yet. You may be able to work through this. If you tell her what you just told me …."

"Eliza, she wouldn't believe me."

More tears fall down her cheeks.

Eliza studies her daughter's face for a few moments. Then she says hesitatingly, "Kara, can I ask you something?"

Kara looks up. She uses her hands to wipe away the tears on both her cheeks and nods.

"There were times when I'd see you and Lena together and I would see how you looked at her and it would make me wonder."

Kara swallows hard. She wasn't expecting this at all. This was something she barely allowed herself to think about. She feels an urge to deny it, laugh it off, pretend she doesn't know what her foster mother is talking about. But she's so tired of the lies, the dissimulation. She sighs.

"I don't know, Eliza. Maybe …."

Kara is startled by a cough from the staircase. A moment later Lena appears in the doorway. There are tears in her eyes.

"Lena!" Kara jumps up.

"I'm so sorry. I shouldn't have listened. I should've let you know I was there."

Kara feels her face turn red.

Eliza gets up. "I'll give you two a minute," she says as she quickly leaves the kitchen.

Kara and Lena stand there, awkwardly looking at each other, both uncertain what to do.

"How much did you hear?", Kara asks.

"I'm sorry. I really should've let you know I was there. But I heard Eliza ask whether you hadn't told me because of my Luthor name and I just wanted to hear you admit it. I wanted to hear you say out loud you didn't trust me. I didn't think you had the guts to admit it to my face."

Lena studies Kara's face for a long moment.

"Kara, I got it all wrong," she finally says.

"Oh Lena, I get it."

A tear falls down Lena's cheek.

"Would it be okay if I gave you a hug?", Kara asks cautiously.

Lena smiles through her tears. She nods. Kara takes Lena into her arms. She hears Lena breathe in deeply as she pulls her closer.

Kara closes her eyes and whispers, "Lena, I'm so sorry."
