Ada was the key.

As much as Alex hated to think about it, as much as she was ready to put a bullet between the woman's eyes, she was convinced that she needed her alive to understand what had happened the night everything went wrong inside the walls of the Settlement.

The only thing they knew for sure is that some kind of ceremony had taken place. The white garments were apparently only worn when something big happened. But as much as Maggie had learned about the rituals and way of life within the cult, she couldn't remember what event had occurred.

At this point, Alex was sure that Ada had faked her amnesia. The agent was convinced that the woman was working along with the Shepard, and stringing Maggie along, manipulating and deceiving her.

"Anything?" She asked while tapping her earpiece, hoping that her sister had captured the woman during her escape. She waited for the other line to beep, before she heard Kara's voice. "Nothing yet. I'll keep looking."

Alex suddenly remembered something. "She said that she was friends with someone at the Daily Planet. Could you see if Clark knows anything?"

"I'll go check. Keep you posted."

Alex turned around with a grunt. She didn't like this one bit – not being in control. Barely having any clue about what was happening.

She made the list in her head. What did they know?

They had Dorian, the whistleblower, who had vanished when the Shepard had taken him from the safehouse. Leaving behind a nearly dead agent as a present to the DEO.

They had North Bridge, whatever it was or meant. A tangible clue that they had yet to decipher.

Maggie, who had changed completely during her stay within the walls, and didn't remember anything leading up to that night.

Ada, a woman that was definitely not on their side of things, that she vowed to keep as far away from Maggie as possible.

And the Shepard – she didn't know what the hell he was. Probably a being from the fifth dimension as far as she could tell, as he had manipulated reality and had an endless list of abilities.

She sighed, rubbing the back of her head. It wasn't much, but it was something. And she had to keep investigating.

She'd left Maggie in the med bay, as Hamilton had the results back from her tests and wanted to follow up. And she'd wanted to be there with Maggie, to support her, to hear what the tests had said. But Hamilton had told her that she wanted to talk to Maggie in private first.

Just in case Maggie wasn't comfortable with Alex hearing about it.

Amelia hadn't said the words literally, but Alex knew what she meant.

So instead of moping around wishing that she could be there for her wife, she flung herself at their investigation.

There was currently an investigative team at the safehouse, once again analyzing the entire house but now looking for clues that Ada could have been involved. Alex knew that it was a lost cause, but at least it felt like they were doing something.

And Winn had searched every database known to man for 'North Bridge', but his algorithm hadn't made a single noise, indicating that it was as stumped as they were.

Frustrated, she leaned on the command center table, browsing through the mission files filled with the transcripts from all of their communications while Maggie was undercover. Maybe she'd missed something.

But her mind kept on wandering off to the med bay.

"The drug we found in your system was consistent with the one found in the other people from the town." Hamilton said, glancing down at her clipboard. "Dosage was the same, so that means you weren't singled out. Everyone had the same thing – whether administered or taken by will, we're not quite sure."

Maggie nodded slowly, unsure how to respond to the news. The doctor sighed. "It's plant-based, just not something we have here on Earth. The bio department is trying to compare it to other specimens we have, maybe we can match it to a certain planet."

"They drugged me a few times when I was there." Maggie admitted. "Always memory loss. There might still be some of it there. I don't know where they'd keep it. Maybe in the bunker."

"I'll make a note of that, someone can go look for it during the next expediti-..."

"Amelia?" Maggie cut the woman off with a frown, looking down at her hands. "Why did you tell Alex that she couldn't be here? What's going on?"

"I… figured that you wanted to process the results on your own."

"Bullshit." Maggie whispered hoarsely, shaking her head. "That's not the reason."

The doctor sighed, lowering her clipboard. "Maggie, you have to understand the kind of pressure Alex is under. As much as you suffered, you have to know that she suffered too."

Maggie frowned, and huffed incredulously. "Y-you think I don't know that?! You think that I don't see the looks she gives me? I'm- I'm trying to be normal!"

The tears came faster than she'd expected, but she couldn't stop them once they spilled, and willed herself to talk through them, sadness replaced with frustrated anger. "I feel so horrible a-and violated and I can't deal with any of it! I didn't ask for it, Amelia… I-it was just supposed to be a couple of days inside, I didn't want to be brainwashed, I-…" She cut herself off quickly, realizing that she was saying things she didn't want to say, least of all to the medic standing in front of her. But Hamilton didn't show any visible response to her outburst, instead nodding slowly.

"I know. And Alex knows that too. But Maggie…" The woman placed a gentle hand on Maggie's shoulder, looking her in the eyes. "You can't let this break you. You're so strong. This is just a bump in the road. You're going to get better."

"She's never going to forgive me for what happened in there." Maggie said, her expression showing nothing but sadness and regret.

Hamilton shook her head. "She wants you to recover from this. Whatever you need. That's what she said, right? So don't think about that. Focus on yourself first. Maybe go talk to a therapist, if you don't feel like talking to anyone here."

Maggie rubbed at her tears with a shaky hand. "She's my handler, I need to talk to her."

"You don't need to do anything you're not comfortable with, Maggie. And she knows that. It hurts, of course it does, but she's willing to do anything for you, if it helps you heal."

Upon seeing that Maggie only managed a small nod, the doctor continued. "There are ways to jog your memory, we've been developing some new ones with some alien technology. It's not on point yet, but should you want it, we can give it a try."

Maggie nodded immediately. "I'd like that, yes."

But not without her Alex.

"Alex?"

She looked up at the sound of her name being called, and saw Winn sitting at his desk. "I might possibly… have something."

Hearing those words made her lightheaded, as she made her way over to his desk, leaning her hand on his chair as she waited for him to start talking. Winn turned to face her. "So… I was thinking... it was probably something that the townspeople wouldn't be allowed to hear. So, what would you do if you didn't want somebody to overhear your important conversation?"

"Code it." Alex replied with a frown. Since she'd seen all of the bridges in the Settlement herself, she doubted that they were talking about an actual bridge – it had to be code.

Winn nodded. "So I'm thinking… What if it's an anagram?"

Alex hadn't considered that in the slightest, but hoped that he was right. She reached for a piece of scratch paper tucked underneath his computer screen, and started writing.

North Bridge

She then started striking through letters, a frown plastered on her face in concentration.

Born Righted

"That makes sense – born righted. Because of the baptism, you get righted again, you're born good again?" Winn supplied. But Alex wasn't satisfied, and tried again.

Bride Throng

"Bride Throng… Maybe the event was a throng -people gathering together to witness someone new becoming one of his brides?"

Her gut feeling told Alex that it wasn't what they were looking for. She scratched through more letters, until she finally shook her head. None of the anagrams made enough sense to be plausible.

She lowered the pen, glancing at the two words on top of the page, that had haunted her dreams ever since she first heard them.

Until she saw it.

Her eyes widened. "Winn, you're a genius."

He chuckled weakly. "Well, I've been told, but-…" He didn't continue, as Alex was already furiously scribbling onto the piece of paper, and circling around what she'd written down.

Rebirth In God

Winn tilted his head. "But that's twelve letters, not eleven…?"

Alex nodded silently, as she wrote down underneath it.

I, North Bridge.

She looked him in the eyes. "We're looking for a person."
