Manuel followed the trail of crushed flowers, and halfway up a steep hill, he found Maria.
"Off exploring?" he asked.
Her tone was neutral, but he somehow knew that she was inwardly cursing. "The types of plants found vary quite a bit with even a small change in altitude."
"Did you know that your suit radio wasn't working? The plants you stepped on were starting to stand back up, so I thought I ought to come check on you while I could still find the trail. It seems to be working fine now, though--I'm not sure what the problem was."
"You don't need to worry. There's nothing dangerous here." She spoke with absolute certainty.
"By the way, did you see another of the bird things? I thought I saw a big one when I was walking here. From a distance, it looked almost like . . ."
"Like what?"
"I'm not sure," he said, and he knew he'd spoken a little too quickly.
She gazed at his eyes through the faceplate of his suit, and he could swear he felt her fingers reaching into his skull.
"I have a headache," she said at last, and together they walked silently back to camp.
He did not tell her what he had seen--what he knew he could not have seen.

The next day, Maria watched Isaac as he knelt to collect a soil sample, and barely within earshot, Manuel watched Maria.
"We're being silly," Maria said. "The Procne virus was a zillion-to-one chance--we've never found another alien microbe that crossed to humans like that."
Isaac bothered neither to look up, nor to turn on his suit radio, and Manuel strained to hear his muffled response. "Are you volunteering yourself to test the air?"
"As a matter of fact, I am. It'll be a pain to go a week without entering the ship, but at the end of it, none of us will have to wear those stupid environmental suits."
At this, Isaac finally met her eyes. "You're the biologist. You should know about incubation periods."
"The Procne virus incubated for five seconds flat. There's not much risk here."
She unscrewed her helmet before he could respond.
It was Manuel who broke the resulting silence. "I wasn't kidding about no kisses for a week."
Maria was much more surprised than Manuel expected. "How long have you been there?"
"Not very long. But you've been acting funny lately, and it's starting to weird me out."
It took Maria several seconds to formulate a response. "Okay, I admit it. I've got ulterior motives in this. Meet me tomorrow, same time and place that we saw the big bird. And as for you, Isaac, if Manuel approves my scheme, I'll be talking to you in a week." With that, she walked off.
Isaac turned to Manuel. "And how are you mixed up in all this?"
"I don't know, but I think I'm about to find out."
Isaac put his hand to his cross. "Take it from the church boy--the girl's possessed."

"I didn't imagine it, did I?" Manuel asked as they stood on the edge of the cliff.
"Didn't imagine what?" Maria was wearing her environmental suit again, and he had no idea why.
"You. 'Light as a feather, soaring the skies.'"
"Light as . . . You read my notebook?"
"I needed to figure out what was going on. For what it's worth, I liked the 'petals of scarlet' poem." Manuel never lied, though sometimes the truth hurt.
