on you, I didn't harass you when we were working together. I treated you exactly as I would have treated any research assistant, except maybe you got away with more because I liked you. You can't ridicule me for responding to you sexually down here when you came on to me. The rules had changed."
"I'm not ridiculing you. Amelia Earhart really is my mother."
"Stop it."
"You want to meet her?"
Nate searched her face for signs of a grin or a tremble in her throat that might indicate the rise of an Amy Ha! Nothing there, just that little bit of sweetness that she usually tried to hide.
"So somehow, living down here, you haven't aged. Your mother?"
"We age, but not like on the surface. I was born in 1940. I'm about the same number of years older than you than you were older than me a half hour ago - kinda sorta. You going to dump me?"
"It's so hard to believe."
"Why, after you've seen all this? You've seen what the Goo can do. Why is it so hard to believe that I'm sixty-four?"
"Well, for one, you're so immature."
"Shut up. I'm young at heart."
"But for a second there I was so sure we were doomed." Nate rubbed his temples - trying to stretch them, maybe - to make his head bigger to hold the whole concept of Amy's being sixty-four.
"No, it's okay, we just haven't gotten to that yet. We're still doomed."
"Oh, thank goodness," Nate said. "I was worried."
Later, after they had pushed the world away for a while, made love and napped in each other's arms, Amy made a move to start another round, and Nate awoke to an immediate and uncertain anxiety.
"Are we really doomed?" he asked.
"Oh, goddamn it Nate!" She was straddling him, so she was able to get a good windup before thumping him hard in the chest with her fist. "That's just un-fucking-professional!"
Nate thought about how the praying mantis female will sometimes bite off the male's head during copulation and how the male's body continues to mate until the act is finished.
"Sorry," he said.
She rolled off him and stared up at dim strips of green luminescence on the ceiling. "It's okay. I didn't mean to bite your head off."
"Pardon?"
"Yes, we're probably doomed. We're doomed for the same reason that I look the way I do, that most of the Goos look much younger than we really are. Turn a gene on, you age; turn it off, you don't. I've even seen some people down here who seem to get younger. Flip a switch, pancreatic cancer at age twenty-two; flip another, you can smoke four packs a day and live to be a hundred. If the Goo thinks that the human race is a danger to it, it just has to flip a switch, pick a gene, make a virus, and the human race would blink out. I hadn't really thought about it as a threat before. My whole life I've worked for the Goo. Service, you know? It takes care of us. It's the source."
He didn't know what to say. Did he need to actually take the Colonel's request for help seriously? Did he need to help find a way to kill this amazing creature in order to save his own species? "Amy, I don't know what to do. Two days ago I just wanted to get out of here. Now? The Colonel and you both said I was lucky to be alive. Has the Goo killed people who were close to finding out about it?"
"Honestly, I don't know. I've never seen it or heard of it happening, but I - we - each just do our own part down here. We don't ask a lot of questions. Not because we're told not to or anything - it's just that you can live a long time without asking yourself big questions when your needs are looked after." For the first time Nate could see the experience of years in Amy's face, marked not by wrinkles but by a shadow in her eyes.
"I'm asking," he said.
"Do I think the Goo is ethically capable of killing the human race?"
"I guess."
"I don't even know if the Goo has ethics, Nate. According to the Colonel, it's just a vehicle for genes and we're just vehicles for memes and nature says that a head-on collision is inevitable. What if it's not? This battle has supposedly gone on for millions of years,
