Lina couldn't sleep.

  She'd tried. Lay in bed for two hours, staring at the ceiling, listening to the city sounds through her window. But her mind wouldn't stop.

  Tomorrow, Jason and RAE would face RP-0. And despite the dangers, still had agreed to help - knowingly.

  She got up. Pulled on clothes. Left her apartment.

  The warehouse was dark when she arrived, but not empty. Light showed under the door to the practice space.

  Inside, she found Elyra. Not sleeping either. Instead, drawing resonance patterns on the floor in chalk, testing configurations, erasing, redrawing.

  "Can't sleep?" Lina asked.

  Elyra didn't look up. "Neither can you, apparently."

  "No - too much going on in my head."Lina said, sitting on the edge of the practice mat. She watched Elyra work for a moment. "Since Jason is not here - please tell me the truth. What," she stopped and fought for words, "what, " she paused and again and Elyra heard the dread and worry in Linas voice, when she continued "What are his chances?"

  Elyra's hand stilled. She kept the chalk in her hands, but straightened slowly. "Of surviving?" Elyra tried to project calm. "Good. We built solid safety protocols. If anything goes wrong, they withdraw."

  "That's not what I asked."

  Elyra met her eyes. "Of succeeding? I'm not sure. RP-0's never been offered a choice before. Might not understand the concept. Might not even be capable of understanding what having a choice means or why it matters."

  Lina shook her head. "That's still not what I'm asking." She took a breath, gathering every bit of courage she had. Then the questions spilled out in a rush: "What are Jason's chances of staying Jason when they reach sixty percent? When the integration gets that deep? How far along are they now? What's their current integration level?"

  Elyra was quiet for a long moment. Then she set down the chalk and turned to face Lina fully. "Fifty-three percent," she said slowly. "RAE mentioned it last week during practice. It's been climbing slowly but steadily."

  "Fifty-three," Lina repeated, feeling the weight of the number. "So they'll hit sixty soon."

  "Within a few months - assuming they keep the pace," Elyra nodded. "And you want to know if he'll still be him."

  "Yes."

  "I don't know."

  The honesty hit Lina like cold water. "You don't know? You studied this. You worked with harmonic entities for years—"

  "With contained entities. Studied patterns. Theory. But actual deep integration between AI and human host?" Elyra gestured helplessly. "There's almost no data. RP-0 killed everyone it tried to couple with. The few who survived weren't integrated—they were overridden or consumed. Broken by force, not merged through partnership."

  "And RAE?"

  "RAE is the only successful long-term integration we know of. Jason is the only case study. There's no baseline. No precedent. No one's ever reached sixty percent through consensual coupling before."

  Lina felt her stomach drop. "So we're just... guessing?"

  "For the most part, yes," Elyra's voice was steady but not unkind. "Educated guesses, but still just guesses. The theory says that around sixty percent, the boundary between host and entity becomes... permeable. Thoughts blend. Memories might overlap. Some researchers believed that's when identity starts to change—not replace, but merge. Becoming something that's both and neither."

  "That's terrifying."

  "For some it might be. For others, it might be exciting." Elyra paused. "But it's also just theory. We don't know because no one's ever done this successfully through consensual coupling. RP-0's victims were consumed or overridden. And after RAE modified herself, weakening the three laws..." Elyra's voice tightened. "The research stopped. Too dangerous. Too ethically problematic. The few scientists who wanted to continue were shut down."

  "So there's no data," Lina said flatly. "No studies. No predictions. We're walking blind."

  "Yes."

  "And Jason knows this?"

  "I've told him what I know and what we assume." Elyra picked up the chalk again, turned it over in her scarred hands. "But I can tell you what I observe. Jason at fifty-three percent is still Jason. Still makes his own choices. Still argues with RAE when he disagrees. Still has his own thoughts, his own fears, his own mind."

  "For now."

  "For now," Elyra agreed. "At sixty percent? Maybe he stays himself. Maybe the integration deepens but his core identity remains intact. Or maybe..." She trailed off.

  "Maybe what?"

  "Maybe he becomes something new, something else. Not Jason. Not RAE. But a synthesis. Something that remembers being both Jason and RAE but isn't quite him nor RAE anymore." Elyra met her eyes. "I don't know which is more likely. I don't know if anyone could know without watching it happen. And even then, I guess it will depend much on the two partners' personalities."

  Lina felt tears threatening, but blinked them back. "So I just... wait? Watch him change and hope he's still in there?"

  "Or you trust him." Elyra's voice was surprisingly gentle. "Trust that he knows himself well enough to recognize if he's losing himself. Trust RAE to honor her commitment to his autonomy. And trust that if it becomes too much, he'll stop and separate."

  "Can he do that? Stop, I mean?"

  "Unknown. Theory says integration can be slowed, maybe stabilized if both parties agree. But stopped completely? Reversed?" Elyra shrugged. "This is just guesses, even in the theories, that exist out there."

  Lina was quiet for a long moment. Then: "This is insane. We're risking everything, for an outcome we can't predict."

  "Yes."

  "And you think we should do it anyway?"

  "I think RAE has chosen to do it. And Jason-deep down inside, without realizing it-has chosen to do it too. That's the only reason I can imagine, why their integration does not stall but progress slowly. This is happening-whether we like it or not." Elyra picked up the chalk and started drawing again. "The only question is whether you stay and support him through it, or walk away because you are too frightened."

  "That's not fair."

  "No. It's not." Elyra didn't look up. "But you asked and I think you deserved an honest answer. You both might not realize it, but I see, that there is more than just friendship between you two. And now he's changing into something you don't understand - we don't understand. And you have to decide if you can love what he's becoming—or if you need to protect yourself and leave."

  Lina felt something harden in her chest. A decision crystallizing. "I will not leave him."

  "Then you have already chosen, to walk into the unknown with him." Elyra glanced at her. "That's brave. Maybe even more, because you're choosing to stay for someone else's journey. Not your own."

  The warehouse went quiet except for the scratch of chalk on concrete.

  The door to the warehouse opened. Milo stepped in, looking tired but determined.

  "Have you been here the whole night?" he asked, glancing between Lina and Elyra.

  "I couldn't sleep." Lina said, forcing a smile.

  Elyra nodded. "Neither could I. We've been going over preparations."

  Milo raised an eyebrow. "Preparations for what, exactly? Beyond the obvious?"

  "Contingencies," Elyra said simply. "What-ifs. Making sure we're as ready as we can be."

  Milo nodded slowly, looking at the chalk patterns on the floor. "Communication channels?"

  "And buffers," Elyra confirmed. "Shield configurations. Ways to establish contact while maintaining separation."

  "Good." Milo sat down, cross-legged on the mat. "Because I've been thinking about what happens if RP-0 tries to rush Jason and force coupling."

  "Exactly, what this is for." Elyra said.

  "And we immediately sever contact," Lina said, in a matter of fact tone. "Immediately. That's the protocol."

  "And the physical positioning?" Milo asked.

  "Mapped out," Elyra said. "Jason approaches from here"—she pointed to a mark on the floor—"maintaining this distance. If RP-0 surges, he can withdraw to these positions." She indicated fallback points with her chalk. "Plus emergency protocols if all three are compromised."

  They spent the next hour going over the plan in detail. Making sure everyone understood their role, their responsibilities.

  By the time they finished, dawn was breaking. Jason had joined them in the meantime, unable to sleep either.

  "Get some rest," Elyra said. "A few hours at least. You'll need it."

  Jason and Lina walked home together as the city woke around them. Silent. Hand in hand.

  At his apartment, she said, "I'm still scared."

  "Me too."

  "But we're doing it anyway."

  "Together," Jason said.

  She kissed him. Not fierce. Just... present. Real.

  Inside, they held each other as morning light filled the room. Not speaking. Just being.

  Are we making the right choice? Jason asked RAE silently.

  I don't know. But it feels like the right choice, the ethical choice. The compassionate choice.

  And if it kills us?

  Then we die having tried to prevent greater harm. That's not a bad ending.

  I'd prefer not dying at all.

  So would I. But some things matter more than survival.

  Jason held Lina tighter. Felt her breath, her warmth, her presence.

  Soon, they'd face RP-0. Offer it choice, boundaries, partnership.

  It would probably refuse.

  But the offer mattered anyway.

  One peaceful moment before the storm.
