“Keep that hand on him,” the tech advised, and went away. Nirgal sat and tried to feel how Sax was doing, tried to feel that vitality struggling in its own processes, swimming back up into the world. Sax’s temperature fluctuated in alarming little swoops and dives. Other medical people came in and held instruments against Sax’s head and face, talking among themselves in low voices. “Some damage. Anterior, left side. We’ll see.”

The same tech came in a few nights later when Nirgal was there, and said, “Hold his head, Nirgal. Left side, around the ear. Just above it, yeah. Hold it there and . . . yeah, like that. Now do what you do.”

“What?”

“You know. Send heat into him.” And she left hastily, as if embarrassed to have made such a suggestion, or frightened.

Nirgal sat and collected himself. He located the fire within, and tried running some of it into his hand, and across into Sax. Heat, heat, a tentative jolt of whiteness, sent into the injured green . . . then feeling again, trying to read the heat of Sax’s head.

Days passed, and Nirgal spent most of them at the clinic. One night he was coming back from the kitchens when the young tech came running down the hall to him, grabbing him by the arm and saying, “Come on, come on,” and the next thing he knew he was down in the room, holding Sax’s head, his breath short and all his muscles like wires. There were three doctors in there and some more techs. One doctor put out an arm toward Nirgal, and the young tech stepped in between them.

He felt something inside Sax stir, as if going away, or coming back— some passage. He poured into Sax every bit of viriditas he could muster, suddenly terrified, stricken with memories of the clinic in Zygote, of sitting with Simon. That look on Simon’s face, the night he died. The perfluorocarbon liquid swirled in and out of Sax, a quick shallow tide. Nirgal watched it, thinking about Simon. His hand lost its heat, and he couldn’t bring it back. Sax would know who it was with hands so warm. If it mattered. But as it was all he could do . . . he exerted himself, pushed as if the world were freezing, as if he could pull back not only Sax but also Simon, if he pushed hard enough. “Why, Sax?” he said softly into the ear by his hand. “But why? Why, Sax? But why? Why, Sax? But why? Why, Sax? But why?”
