"I didn't know that I had it in me to be happy. Until Maggie, I didn't know that I had it in me to love someone, like really love someone," Alex admits tearfully.

Kara wraps her arms around her sister a little tighter and lets her cry on her shoulder. Tears of her own slightly falling as she understands this feeling.

"You'll find happiness again Alex. There is someone out there who is perfect for you, what do they call it?" Kara murmurs into her hair.

"Soul mates," Alex supplies. "I can't believe that you believe in soul mates," she says pulling away from her sister and leaning back against the headboard of the small bed.

Kara shrugs, but before she can respond Alex continues.

"Wait. What if Maggie was mine and now I've fucked it all up because I wanted more than she could give?"

"Maybe you get more than one," Kara suggests. She had finally got her sister calmed down enough to talk, but now she's cursing again.

"I was lucky to find her. I am an idiot for wanting more than her. And why are we here? This room just reminds me of all the lies that I told myself growing up. Everything that I suppressed, I learned to suppress here in this room," Alex says angrily before reaching for the bottle to pour herself a bit more scotch.

"Hey, don't you think that's enough scotch for tonight?" Kara asks a bit nervously.

"It doesn't matter how much I drink, now that we're here. It's not like Mom's going to let me out of the house until I talk about my feelings. Thanks for that by the way," Alex snaps.

"I was just trying to help you. You were sad and drunk Alex. But if you're going to be mean and drunk, I'm going to sleep in my own room," Kara replies sharply.

"Fine. I can drink alone. Which is perfect, since I will have to, now that I've gotten rid of the one person who ever made me happy," Alex grumbles.

"Tomorrow we can go for a hike and talk, you'll feel better if you talk about it... sober," Kara suggests pointedly.

"Talk about it? Oh, that's rich coming from you. I've been trying to get you to talk about what happened with Mon-El for over six months. You've bottled it up so tight, you probably have Kombucha by now," Alex argues loudly.

The blonde scrunches her face in frustration. "It's not the same," she retorts. "What I had with Mon-El wasn't the same as what you had with Maggie."

"What do you mean? You guys were together. You lived together. He's like the only person, other than me, that you've ever let that close," Alex sets her glass down now and leans forward.

Kara stands up and walks over to the window. Before Alex can respond, she floats out and is gone.

"Hey, come back here. Kara, we're talking about this right now," Alex yells before slipping out the window and climbing onto the trellis to go up to the roof. A little tipsy, she misjudges her footing causing her to swing out wildly.

Kara swoops in and grabs her before she can spiral down into the bushes below.

"You're too drunk to climb up to be out here," she grumbles at her as she pulls her up, then drops her onto the flat section of the roof.

"I'm fine, I didn't need any help," the brunette grumbles as she sits up carefully. "Now what did you mean about Mon-El and you? Are you saying that him leaving didn't affect you? Because I am totally calling bullshit on that."

Kara floats down and sits beside the brunette. "Remember when you used to say that you weren't built for relationships? You said that it just wasn't your thing?"

"Yeah, but I was wrong. Maggie proved that. She made me realize that I wasn't being honest with myself about who and what I wanted," Alex remarks, suddenly sounding sober.

"It's not the same with me. I really don't have the capacity for that level of relationship. I was never in love with Mon-El, I just, well, he was the only alien like me on the planet, so I just felt like I should be with him," Kara explains.

"Wait, you're saying that you were only with him because he was an alien?" Alex questions.

"Daxamites were practically Kryptonian, so yeah. I was with him because it seemed like that was my only option. And he was attractive, annoying most of the time, but sometimes he could be sweet," Kara admits.

"Oh god Kara. I should have realized that was why you were with him. He was so fucking annoying. I wanted to put on the exo-suit and kick his ass so many times," Alex retorts angrily.

"Alex, it was fine. It's not like I have a lot of options here. Let's face it, I could kill a human in my sleep," Kara reminds her.

"No, you couldn't. You wouldn't. Remember that time I was sick and you didn't leave my side the whole weekend. We stayed in and binge watched Homeland, we slept side by side and never once did you hurt me," Alex reminds her, suddenly letting go of her own pain, now that she understands why Kara wouldn't talk about Mon-El.

"Well, I didn't really sleep that weekend. I don't usually sleep when someone else is there," Kara admits sheepishly.

"Seriously? But you did sleep with Mon-El?" Alex asks quickly.

"Yeah, of course. I guess sex makes all species sleepy," Kara retorts.

"TMI!" Alex grumbles. "I'd rather not think about you having sex with him, especially if you didn't even love him."

"I loved him. I just wasn't in love with him. At least I don't think I was, because I saw how you and Maggie were and we, we weren't like that. Not even close. It was more like friends who also had sex," Kara explains.

"Great, you had a fuckboy. Well, there are worse things, I suppose, but you deserve more than that," Alex asserts.

"Thanks," Kara acknowledges the remark, but it's obvious that she doesn't agree.

Alex shakes her head. "You have a huge capacity for love Kara. You just need to let yourself do it, let yourself fall in love with someone and it won't matter if they're an alien or a human. Your cousin is with a human, so there must be ways to make that work."

"I am not asking Kal-El about having sex with humans," Kara replies sharply.

"I can ask him for science," Alex remarks. "It's not like we have done much research in this area. Which should probably change. What if Lois got pregnant? Or what if you did?"

"We aren't human Alex. It doesn't work the same for us as it does for humans," Kara reminds her.

"But how does it work? I should know this. I'm the leading authority on Kryptonians," Alex replies.

"Actually, I am the leading authority on Kryptonians. And if you really want to know, then we can go up to the Fortress sometime and you can research it there in the archives," Kara offers.

"You'd really take me to the Fortress and let me do that?" Alex asks.

"If it gets me out of this conversation, yeah." Kara says exhaling dramatically.

"I owe you an apology," Alex murmurs.

"Sorry, didn't quite hear that," Kara jokes, nudging her sister with her shoulder.

"I'm sorry. I was an ass the whole drive here and then I holed up in the room and drank all night. I am officially the worst sister," Alex exclaims dramatically.

"In your defense, you did just go through a bad break up," Kara offers, giving her a hug. "And I will accept your apology, only if you promise that we can leave this house tomorrow. I can't stay cooped up in here any longer."

"We can do that, but right now I want you to really talk to me," Alex retorts. "You really think that you can't fall in love?"

"I don't think that I can. I saw what you and Maggie had and I tried to feel that with Mon-El, but it wasn't the same," Kara explains.

"But you must have loved him, you were upset after he left," Alex murmurs struggling to figure out what she means.

"I failed to protect him. I wasn't able to defeat Rhea without putting him in danger," Kara snaps.

"It wasn't a fair fight. You fought her as hard as you could and remember that you had practically blown out your powers fighting your cousin," Alex points out.

"Yeah, I beat Kal-El to become the world's champion, only to almost lose everything I fought for," Kara grouses.

"You can't be so hard on yourself Kara, you're only h..." Alex is about to say human when Kara interrupts her.

"Alien. Alex. I'm not a human and I need to stop pretending to be. I am an alien and while I may look human, I'm definitely not." Kara floats up off the roof for emphasis.

"I know that you're not human, but it's not as though you are inhuman. Kara, you have an amazing capacity for love. I've seen it in action. And you love unconditionally, which is something that I am still working on," Alex retorts standing up and holding out a hand to pull Kara back to the roof.

Instead, Kara pulls Alex up into her arms.

"I need to fly. Come with me?" She asks.

Alex nods and wraps an arm around the hero.

Kara doesn't 'love'. She didn't realize it because Alex was the same way. Then Alex met Maggie and Kara saw what 'love' looked like so she tried to 'love' Mon-El and thought that she did to a degree. She was sad to see him go, but now that Alex and Maggie are over, Kara can see that what she had with Mon-El wasn't even close to human love. And since she isn't human maybe she doesn't have the capacity for love.

Lost in her own thoughts, it takes Kara a moment to realize that Alex is shivering in her arms. She adjusts their position so that Alex is in front of her and then wraps around her body, before turning them around to head back to the house.

"Feeling better?" Alex asks hopefully when they step back into the bedroom from the roof.

"Maybe trying to be Kara Danvers was a mistake," Kara offers before turning back to the window and looking out at the stars. "Kal-El may be able to fit in here, but I never really have. Maybe I would be happier if I was just Kara Zor-El again."

"Kara Zor-El and Kara Danvers are the same person," Alex insists as she steps in front of the window. "Kara, you never stopped being Kara Zor-El."

"I did though. I had to, that Kara doesn't exist here on Earth. She can't, because if she did, the DEO would have locked her up," Kara spits out angrily.

Alex takes a step back, when Kara's eyes flash orange for a millisecond.

"That was the old DEO, that was when Hank Henshaw was in charge and everything has changed now. You can be both," Alex reminds her softly.

"No Alex. No, I can't be both now or everyone will know my secret identity. I hate lying to Cat and Lena, now I'm lying to Sam and Ruby. How Lena hasn't figured it by now is beyond me, she is probably pulling a Cat Grant and just protecting me by not letting on that she knows," Kara suggests wryly.

"You don't have to lie to Cat Grant any longer, she knows your secret and the President's. You can be yourself with her," Alex points out.

"Yeah right, Cat and I are BFFs all the sudden," Kara grouses.

"You could be, she cares for you a great deal. I've witnessed it with my own two eyes, Kara." Alex argues.

"Whatever you saw wasn't what you think you saw. What does Kal-El call it? Cape effect?" Kara grumbles.

"Seriously, you think that Cat Grant is only interested in you because of the cape?" Alex asks.

"Of course, not like she was interested in anything about me before she started to think that I was Supergirl," Kara retorts.

"Before you were Supergirl, you were her assistant for two years... She's never had an assistant that long. There was something about you that she liked or she wouldn't have kept you around," Alex remarks.

Kara scoffs and bites back another retort, before going over to sit on the bed.

"I'm tired. Can we stop talking about this now?" She asks before stretching dramatically and laying back on the bed.

"Yeah, of course. But are you okay? I don't want you to just lay in here awake all night thinking. Let me stay and snuggle in, it used to always help you sleep," Alex offers sitting down on the edge of the bed.

"I'm not a lost little girl anymore, Alex. I have been getting myself through nights like this a long time now," Kara mumbles rolling away from her sister.

Alex looks at her back a moment before making a decision. "Doesn't mean you have to tonight though," she says settling in behind her and assuming the big spoon position.

"You're not big enough to be the big spoon," Kara murmurs, but her body relaxing into the embrace gives her away.

Alex smiles softly and nuzzles her hair. "Just sleep sweetheart, I've got you," she says softly to her sister.
