"...Lvov? Are you okay?"
She was panting, she found. "I'm fine."
"You were screaming."
"Was I? I'm sorry. I fell."
"You fell? How?"
"There was a hole, in the ice." She massaged her left ankle; it didn't seem to be hurt. "It was covered up."
"Show me."
She got to her feet, stepped gingerly back to the open hole, and held up her data desk. The hole was only a few inches deep. "It was covered by a sort of lid, I think."
"Move the desk closer to the hole." Light from the desk, controlled by Cobh, played over the shallow pit.
Lvov found a piece of the smashed lid. It was mostly ice, but there was a texture to its undersurface, embedded thread which bound the ice together.
"Lvov," Cobh said. "Take a look at this."
Lvov lifted the desk aside and peered into the hole. The walls were quite smooth. At the base there was a cluster of spheres, fist-sized. Lvov counted seven; all but one of the spheres had been smashed by her stumble. She picked up the one intact sphere, and turned it over in her hand. It was pearl-gray, almost translucent. There was something embedded inside, disc-shaped, complex.
Cobh sounded breathless. "Are you thinking what I'm thinking?"
"It's an egg," Lvov said. She looked around wildly, at the open pit, the egg, the snowflake patterns. Suddenly she saw the meaning of the scene; it was as if a light had shone up from within Pluto, illuminating her. The "snowflakes" represented life, she intuited; they had dug the burrows, laid these eggs, and now their bodies of water glass lay, dormant or dead, on the ancient ice...
"I'm coming down," Cobh said sternly. "We're going to have to discuss this. Don't say anything to the inner System; wait until I get back. This could mean trouble for us, Lvov."
Lvov placed the egg back in the shattered nest.
She met Cobh at the crash scar. Cobh was shoveling nitrogen and water-ice into the life-support modules' raw material hopper. She hooked up her own and Lvov's suits to the modules, recharging the suits' internal systems. Then she began to carve GUTdrive components out of the flitter's hull. The flitter's central Grand Unified Theory chamber was compact, no larger than a basketball, and the rest of the drive was similarly scaled. "I bet I could get this working," Cobh said. "Although it couldn't take us anywhere."
Lvov sat on a fragment of the shattered hull. Tentatively, she told Cobh about the web.
Cobh stood with hands on hips, facing Lvov, and Lvov could hear her sucking drink from the nipples in her helmet. "Spiders from Pluto? Give me a break."
"It's only an analogy," Lvov said defensively. "I'm an atmospheric specialist, not a biologist." She tapped the surface of her desk. "It's not spider-web. Obviously. But if that substance has anything like the characteristics of true spider silk, it's not impossible." She read from her desk. "Spider silk has a breaking strain twice that of steel, but thirty times the elasticity. It's a type of liquid crystal. It's used commercially -- did you know that?" She fingered the fabric of her suit. "We could be wearing spider silk right now."
