Ianto watched as Sulu took measurements about the plant, readings and statuses and the likes, before stepping off to the side to examine the fish more closely. From the size that they were, honestly, Ianto was having a hard time trying to come up with just how they would catch one and then lug it back to somewhere where there was enough open space to roast it or do any sort of barbequing whatsoever. It was sort of intriguing, though, the idea that they could do something like that. Definitely more adventure than Ianto ever got up to there. On a normal camping trip, that was.

But then something rustled in the trees along the river, and though it was soft, it was definitely the sound of something other than the wind. Ianto, standing closer to the other side and less preoccupied than the other man, heard it quite clearly. He took a step back, a step closer to Sulu, because really. He'd heard what birds sounded like, and they didn't sound like that, and Sulu'd insisted that there were only birds and fish there, and fish didn't move in the leaves, so. "...did you hear that?" he asked, cautiously, his eyes not leaving the treeline where he'd heard the rustling even as he inched his way back to where Sulu was.
