Chapter 75: Beneath the Seam

Sarah had joined them by the time Carrick settled Jonah’s left hand on a folded cloth again. She stood near the end of the table with both hands around a cup she had stopped drinking from. Ruth’s earlier sensory map lay open beside the newer one, the second line reaching farther toward Jonah’s wrist.

Rafael had cleared a place for his field book. Leo and Armin kept to the wall, leaving Carrick and Ruth room around the instruments.

Carrick tapped the newer line with one finger. "Before, a larger sample wasn’t worth cutting healthy skin. Since then, the numbness has spread. The piece from the seam didn’t look like the normal side, and the refuge sample showed the same unusual branching."

Jonah looked at his hand. "And where my hand was."

"That may matter too." Carrick folded the older map back. "We can still wait. But if we do, we’re watching this spread without knowing what’s happening under the skin."

Jonah looked up at him. "So what do you want to do?"

"A small cut at the edge of the numb area. Small enough that I can close it here. I want to see what’s under the skin on both sides, where you can still feel normally and where you can’t."

Jonah asked about the risks. Carrick answered plainly. "There could be bleeding or infection. I could damage a small nerve or vessel and make the numbness worse. And after all that, we may still learn nothing."

"That last one sounds familiar," Jonah said.

"Unfortunately."

Sarah set the cup down. "If this makes it worse, can you fix it? And how do you know cutting into it won’t make it spread?"

"I may not be able to fix it." Carrick did not reach for reassurance. "And I don’t know whether cutting into it could make it spread. I can’t promise it won’t make the numbness worse."

Jonah glanced at him. "You’re terrible at selling this."

"I’m not selling it."

Jonah turned his palm up and watched the last two fingers flex. "If we do nothing?"

"Then we keep watching. If your grip weakens or the numbness moves again, we come back to this. But I still won’t know what’s under the skin."

"So I risk it now, or I wait and maybe there’s more to lose."

Carrick considered that. "Yes."

Jonah looked at Sarah. She did not tell him what to do.

Jonah breathed out through his nose. "Then cut the bloody thing. Small means small."

"It will be."

Ruth pulled the older map closer and began again with the blunt probe. She worked only across the narrow strip where the previous line and the new one no longer matched, marking where sensation weakened and checking the same points from the opposite direction. Carrick repeated the test himself before choosing the site.

Severin watched Carrick compare both maps before reaching for anything sharp.

Rafael copied the location into his book. "That’s the edge?"

"The best boundary we have," Carrick said.

He cleaned Jonah’s hand while Ruth laid out the instruments. Whatever Carrick used to dull the pain went into the chosen strip in small amounts. Jonah kept his eyes on Severin instead of the needle.

"You can look somewhere else," Severin said.

"I am."

"You’re looking at me."

"Exactly."

Carrick waited, tested the skin again, then began. Severin had seen uglier wounds, but those usually came with an explanation. Carrick was making this one because none of them had one.

Blood welled along the first shallow opening. Ruth dabbed it away before it could run into Carrick’s working area. He extended the incision only a little farther across Ruth’s mark, then paused when the bleeding thinned.

"Less there," Ruth said.

"Yes."

Carrick changed the angle of the lamp. The difference was too small for certainty. He said vessel placement or nearby scarring could explain it. Rafael wrote the observation down without turning it into more than Carrick had claimed.

Then Carrick stopped speaking.

Severin shifted closer. At first the pale line beneath the lamp looked like another wet reflection, but Carrick touched its edge with the tip of his forceps and the color remained.

A strand no thicker than coarse thread passed through the exposed tissue, too pale against the red around it. Farther in, a second branch split away. The two lines curved around a patch of ordinary flesh before meeting again beneath the skin.

Ruth leaned over Carrick’s shoulder. "That’s the same shape."

Rafael had the refuge drawing open before she finished speaking. Ruth glanced from the exposed hand to the sketch and followed one branch on the page with the blunt end of her pencil, stopping where the lines joined again. She did not name it.

Severin did not need the drawing. He had watched water freeze over one branch of that pattern two nights before while the other stayed wet. The refuge chip had carried Leo’s vibration differently along the same split.

On paper it had looked useful. Inside Jonah’s hand, the resemblance was harder to keep at the level of lines and measurements.

Carrick adjusted the lamp but opened nothing farther. The pale structure continued beyond the incision in both directions. He said unusual scarring or connective tissue change might still explain part of what they were seeing, but the branching gave him no answer he trusted.

"You couldn’t see that from the surface," Sarah said.

"No."

Jonah tried to raise his head. "Can I?"

Carrick shifted his arm rather than blocking him, and Ruth held the lamp so Jonah could see without twisting the hand. Jonah studied the opening for several seconds.

"Was that in me before the refuge?"

"I can’t tell you."

"Since the drowning?"

"I can’t tell you that either."

Jonah lowered his head again.

Severin looked from Sarah’s untouched cup to Rafael’s field book, then back to Jonah’s hand.

Carrick took one fine strand between the forceps. "Tell me if you feel anything."

Jonah nodded.

Carrick lifted by a fraction. The pale strand rose with the flesh beside it, and he released both immediately.

Armin stepped away from the wall. "They moved together."

Carrick looked at him.

"Barely. But the flesh moved with it."

Rafael added the observation to the page.

Carrick changed tools. Instead of lifting again, he used the rounded end of a probe and touched the exposed strand with almost no visible pressure. "Anything?"

"No."

He shifted to another point.

Jonah’s smallest finger flexed.

The movement was slight enough that Severin might have doubted it if Jonah had not stared down at his own hand.

"I didn’t do that."

Carrick removed the probe and waited for the finger to settle. Then he touched nearly the same point again, more carefully than before.

The finger drew inward a second time.

Jonah kept watching it. "Still nothing."

Severin replayed the movement in his head. Carrick had not pulled the strand that time. The probe had barely displaced it, yet the finger had moved farther than the pale line beneath the skin.

Armin seemed to reach the same conclusion; he leaned closer to Rafael’s notes and quietly described the direction of Carrick’s touch compared with the finger’s flexion.

Ruth looked from the hand to Carrick. "A nerve?"

"I don’t know." Carrick set the probe aside. "The probe is causing the movement. I’m not going any further."

Leo nodded toward the opening. "Can you tell where it leads?"

"Not without opening more of his hand."

"Then don’t."

"I wasn’t going to."

The seam had been the place where they first found pale material. Now a finer version of it ran under skin that had looked ordinary that morning.

Carrick selected the smallest useful section at the edge of the opening and explained the next step to Jonah.

"I want a tiny piece from each side. One from the normal edge, one from the pale side. I won’t go any deeper than I already have."

"If you cut that, can you make the numbness worse?"

"Yes. I can’t tell you how likely that is."

"Right." Jonah kept watching his hand. "Take what you need."

Ruth prepared two small dishes and marked them before Carrick cut anything. Rafael repeated the labels aloud and copied them into his notes.

Carrick removed the ordinary comparison first. The piece was so small Severin nearly lost sight of it when Ruth transferred it to the dish.

The altered sample took longer. Carrick cut only the exposed end of one pale-bearing branch with the surrounding tissue attached. When it resisted, he changed the cut rather than pulling, freed the smallest piece he could use, then put the instrument down.

Jonah flexed his fingers when Carrick asked him to. The last two answered, though the smallest lagged enough for Carrick to test it again.

"No worse than before?" Carrick asked.

"Feels the same."

"That doesn’t tell me much yet. Ruth will check it again once I’ve dressed this, and again tomorrow morning."

Carrick closed the small incision while Ruth assisted, then watched the dressing for fresh bleeding. Only after Jonah’s hand was wrapped and secure did he turn toward what they had removed.

Severin stayed beside Jonah. Sarah moved closer and rested a hand on Jonah’s uninjured arm. Across the worktable, Rafael and Armin took positions where they could see without touching anything.

Leo stood at Carrick’s shoulder while Ruth set both dishes beneath the lamp. The ordinary sample lay where she had placed it; the altered piece held a pale strand across one cut edge.

As Severin watched, that edge drew inward, only slightly.

Ruth frowned and picked up a fine instrument. "Wet tissue can shift."

She eased the curled strand straight and removed the instrument. Nobody moved around the table.

For several seconds the strand stayed where Ruth had left it.

Then the cut pale end slowly drew back toward itself.

Carrick said nothing.
