Cloud stopped; loosed her mind. “I’m sorry, chick, but I was just getting nicely organized. We’ve got a long ways to go yet, I’m afraid.”

“I’m sorry, too, Storm, sorrier than you’ll ever know, but I simply can’t take it. Three seconds more of that and I’d’ve gone stark, raving mad. And when we get to Cahuita I don’t know what I’ll do. I may blow up completely.”

“You may think so, but you won’t. You’re not the type. And we aren’t going to Cahuita—at least, not in the flesh. When we hit that band we’ll be there automatically.”

“Not quite automatically, of course, but we’ll be there, yes. I want to stay with you, more than I ever wanted anything before in my whole life, and I want to help you . . . couldn’t we loosen the fusion just a little, so that I can pull away when the going gets too rough for me? Just enough to keep away from a burnout, but close enough to see and perhaps to help a little?”

“I don’t know why not . . . sure, like this.” He showed her.

Again the fusion went up and up and up, and this time it did not stop at Joan’s ceiling. She pulled away a little, but not enough so that she could not sense and understand, in a way, what was going on.

Cloud, every muscle set and eyes closed tight, sat in a chair, his hands gripping fiercely its arms. Joan lay face down upon a davenport, her face buried in a pillow, her fists tight-clenched.

And the linked minds—linked now, not fused—went up . . . and up . . . and up. . . .

And, finally, they reached the band upon which a Cahuitan fulfillment was thinking.

It would probably be too much to say that the fulfillment was surprised. An adult, fulfilled Cahuitan is so serene, so sedate, so inherently stable at any possible level of stress, that it is probably impossible for it to feel any such sensation or emotion as surprise, even at the instantaneous unveiling of a whole new universe of thought. It was, however, in a calm, passionless, and scholarly way, interested. Not what could be called intensely interested, perhaps, but really interested, nevertheless.
