Alex paced the DEO. Maggie watched her, not sure what to do. There was nothing she could do. Kara was off at the Fortress of Solitude getting rid of the fifth dimensional guy. By herself. By way of agreeing to marry him.

Mon-El had rushed in with the news about an hour ago. He had been desperate for Alex or J'onn to do something. J'onn hadn't been happy to hear of Kara's plans but he explained that there was no way into the Fortress if Kara sealed it. Not a gambling man but he said he'd put good money that she had. Specifically so no one, like J'onn and Alex, could stop her.

The mood around the DEO was somber. No one knew what it meant for Kara to marry this interdimensional being. Could she stay in National City? Could she still be Supergirl? Alex seemed to be answering no for both those questions. Danvers Crinkle out with a vengeance as she paced. One hand resting on her holster.

"Alex," Maggie started. To say what? No clue but she had to try.

"Oh my god." Alex stopped and looked at Maggie, who was now wide-eyed and curious at whatever Alex was about to say.

"What?"

"I have to tell Sam." Alex's shoulders slumped.

"Couldn't you wait? Maybe see what happens before we let her know."

"No." Alex shook her head, pulling herself back together. Agent Danvers showing through but Maggie was coming to see the subtle difference of between the agent and Alex's strong big sister persona. "Not after we didn't tell her right away about Dad. I need to tell her now. I won't make that mistake twice."

"Okay."

Alex hesitated after she pulled her phone out. She looked around then back at Maggie. "Will you come with me?"

Maggie nodded. She would have loved to take Alex by the hand as she followed her to a conference room but she didn't. Not at the DEO. Instead, Maggie flashed her best comforting smile when Alex turned away from the now closed door with big doe eyes full of worry.

They stood in silence as Alex dialed Sam then waited for her to answer.

"Hey Sam."

"No. This isn't DEO-related. Well, not really."

"I need you to hear me out."

"It's, uh. It's Kara actually."

"Sam, wait. Please. I know you don't want to talk about Kara and it's not about that. I promise but…Sam, seriously. Just listen."

"Sam!" Maggie was surprised Alex raised her voice. She couldn't imagine what Sam was saying on the other line. More than Alex's raised voice, she was surprised Sam was even still on the line. "Something happened and I need you to listen to me. This isn't the time for our family bullshit."

Alex took a deep breath. Her eyes staying connected to Maggie's. "The other night, this guy showed up. He's from another dimension and came to ours because he wants to marry Kara. She said no but he started causing trouble. Mon-El came to the DEO and says that Kara agreed to marry him at the Fortress of Solitude. We don't know what happens once she marries him. We don't know anything."

Silence enveloped the room. Maggie was sure the line was silent too. She wondered what Sam thought about all this, how she was reacting. Maggie thought she had Sam down at this point in their friendship. She thought she knew her pretty well. The broken little girl that fueled the bristle and thorny armor Sam put on wasn't really Sam. Maggie was sure there was more in there. That's how Alex was and both sisters needed to heal to better be themselves. Alex was already on the way.

"I don't know." Alex looked away from Maggie then. Ashamed that she didn't know whatever Sam just asked.

"No." Alex's eyes narrowed. "No."

Now Maggie was really curious. This conversation was much more than what either of them expected.

"Okay. Let me know if you see her or hear from her, okay? We have no idea what happens after the Fortress…Bye." Alex hung up and took a deep breath.

"What'd she say?"

Alex smiled. Worry still colored the edges though. "She's pissed as hell Kara would do something so stupid. Exact words, Mags."

"That's kind of awesome! Shitty situation but that's a step in the right direction."

"I know!" Alex slipped her phone into her back pocket and sat down. Maggie stayed on her feet but leaned against the table next to Alex. Close but professional enough for work. "At first, Sam was an ass. She didn't want to talk to me and got even more bratty when I told her I wanted to talk about Kara."

"But then she listened?"

"And got upset that Kara was doing something so insanely stupid."

Alex's excitement over Sam was overcome by her worry for Kara. Maggie felt for her. There just wasn't anything an NCPD detective could do when it came to an interdimensional being eloping with her girlfriend's sister. Even with her science division experience, this was a little out of her wheel house.
