Chapter 3
The second day Melissa waited for something to go wrong.
She’d done it consciously, the way she’d once scanned sectors — systematically, without prejudice, looking for the thing that would confirm what she already suspected. That this was a mistake. That having another presence in her space would erode the carefully constructed functionality of her life in ways she hadn’t anticipated. That Rika would move something, break something, misunderstand something fundamental about how the apartment worked and why it worked that way.
Nothing went wrong.
Rika moved through the apartment like she’d always been in it. Not invisibly — Melissa was always aware of her, the way you were aware of weather, a background condition that registered without demanding attention — but without friction. She cooked. She cleaned. She handled the laundry with the same thoroughness she apparently brought to everything, folding things in a way Melissa had never bothered with and leaving them in exactly the right places.
The high shelves got restocked. Not reorganized — restocked, things returned to where Melissa had put them, just reachable now without the grabber she’d been using for three years.
She hadn’t asked for that either.
On the third day the phantom pain came.
It announced itself the way it always did — not with pain at first but with presence, the ghost geography of legs that hadn’t been there for fourteen years making themselves known. Her left thigh first, then the right, the deep bone-ache that had no bone to live in settling in around midnight with the comfortable familiarity of an unwelcome houseguest who knew where everything was.
Melissa sat up in the dark and breathed through it the way she’d learned. Not fighting it, not feeding it. Just letting it move through her like weather.
She heard nothing from down the hall.
Then, softly, a knock.
Rika came in without turning on the light. She was carrying a heat wrap, already warmed to the right temperature — not so hot it burned, warm enough to matter — and she sat on the edge of the bed and pressed it against what remained of Melissa’s left thigh where the phantom sensation was worst and said nothing at all.
Melissa said nothing either.
The heat moved into the tissue the way heat did and the pain didn’t vanish — it never vanished cleanly — but having someone in the room changed the weight of it. She sat in the dark with Rika’s hands holding the wrap in place and breathed and let the pain loosen its grip degree by degree until it was something she could put down rather than something carrying her.
When her hands relaxed flat against the mattress Rika lifted the wrap. Rose from the bed without a word.
“How did you know?” Melissa asked.
Rika paused in the doorway. The light from the hall caught the edge of her profile — the straight line of her nose, the fall of dark hair over one shoulder.
“You were pressing your hands against your legs,” she said. “You do that when it starts. You don’t notice you’re doing it.”
Melissa hadn’t known that about herself. Fourteen years and she hadn’t known that.
“It’ll come back,” she said. Meaning the pain. Meaning don’t make this into something.
“I know.” Rika’s voice was the same temperature it always was. “I’ll hear you.”
She pulled the door to behind her. Not closed all the way. Just to.
Melissa lay back down and looked at the ceiling and listened to the apartment settle around her. Outside a car passed on the wet street, headlights moving across the ceiling in a slow arc.
She hadn’t asked for help.
Rika hadn’t asked permission.
Neither of those things had stopped it from being exactly right and Melissa didn’t know what to do with that so she did what she always did with things she didn’t know what to do with. She filed it under data pending and closed her eyes and waited for morning.
She didn’t reach for the medication.
She didn’t need to.
The fourth day she watched Rika more carefully than she had before.
Not obviously. She was a door gunner — she knew how to observe without appearing to observe. She went about her morning the way she always did and tracked Rika in her peripheral vision and tried to identify what it was about her that kept slipping past Melissa’s defenses.
It wasn’t the competence. Melissa had expected competence. She’d paid for competence.
It was the quality of attention.
Rika paid attention to everything with the same completeness. The pan on the stove and the light coming through the window and Melissa’s coffee mug and Melissa herself all received the same quality of regard — present, unhurried, missing nothing. There was no hierarchy to it. She wasn’t performing attentiveness. She was simply paying attention the way some people were simply tall.
It was, Melissa thought, the most unsettling thing about her. More unsettling than the eyes, more unsettling than the way she moved.
You couldn’t catch her not paying attention.
She’d tried.
In the afternoon she worked and Rika was elsewhere in the apartment and at some point Melissa became aware of a sound she couldn’t immediately identify — a soft rhythmic something from the direction of the second bedroom. She wheeled to the doorway and looked in.
Rika was sitting cross-legged on her bed with Melissa’s laptop open beside her and a small notebook in her lap, writing something in characters Melissa recognized as Japanese. She looked up when Melissa appeared in the doorway. Didn’t close the notebook. Didn’t appear startled or guilty.
“I’m sorry,” she said. “Did you need the laptop?”
“No.” Melissa looked at the notebook. “What are you writing?”
A pause. Not hesitation — consideration.
“Observations,” Rika said.
“About what?”
Those black eyes steady and untroubled. “About you.”
Melissa looked at her for a long moment.
“Show me.”
Rika held out the notebook.
The characters were dense and precise and completely unreadable to Melissa, which Rika had presumably known when she answered honestly instead of deflecting. She looked at the pages — three of them filled, small careful writing — and handed it back.
“What does it say.”
“That you take your coffee black with one sugar but you prefer it slightly less sweet than the questionnaire indicated and I’ve been adjusting.” A pause. “That you position your chair at an angle to the kitchen door that lets you see both the room and the hallway simultaneously. That you sleep on the left side of the bed even though the right side is equally accessible.” Another pause. “That you have a consulting deadline on the fourteenth and you’ve been working ahead of it, which means either you expect an interruption or you’re in the habit of finishing early.”
Melissa said nothing.
“That you haven’t opened the drawer in your bedside table since I arrived,” Rika said. “And that whatever is in it, you check whether it’s still closed every morning when you wake up.”
The apartment was very quiet.
“You noticed that?” Melissa asked.
“I notice everything,” Rika replied. Not boastful. Just accurate. “It’s what I’m for.”
Melissa looked at her sitting on the bed with her notebook and her precise careful writing and those eyes that missed nothing and thought about the drawer in her bedside table and what was in it — the photograph of Dexter and Rodney and herself on the flight line at Fort Campbell, taken six months before Fallujah, all three of them squinting into the sun and grinning at whoever was holding the camera.
She didn’t open that drawer often. When she did she didn’t look at the photograph for long.
“You’re not going to ask,” Melissa said.
“No,” Rika answered.
Melissa wheeled back to the living room.
The fifth day the outdoor companion feature activated.
Melissa was at the kitchen table with her second cup of coffee when Rika appeared in her jacket — a light one, gray, the June morning outside still cool enough to warrant it — and set a travel carrier with two cups on the counter.
