Isaac didn't like this place much, but he had to admit he was relieved that there was color here. The clothing could have been better, too, but his technology wasn't acting up and his heart rate was mostly regular, so he was productive.
Eleni wasn't around either, the group seemed to be halved, even though it was always growing. He could see the other island, though, and though he hadn't heard of anybody making it there he did plan on setting up some smoke signals to see if there was life there. If his sister was alright and saw the signals she'd be able to send some up as well, and they could work from there.
He set up the signal near the beach facing the other island, stacking wood and leaves and building a sizeable pile. In his work he removed all of his clothing except for his pants, putting it off to the side. Taking some sticks he set about making fire. He'd avoided the other people on the island so far, none of them seemed to have anything more than he had, so there was no benefit to playing nice. He would make the fire, and if there was another on the other island he could work out a net of leaves to block the fire's light at will. Morris code was something both Stark children knew, and would facilitate an update on how Eleni was doing. And then... well, he supposed they would wait to be sent somewhere new, or for something to happen.
It took some time for him to get the wood to create flame, and he took breaks to find water and gather a few of the wild carrots, but eventually he got a good fire going, creating a satisfactory bonfire that he loaded with leaves to make as smokey as possible. The column of smoke heading up was thick and very visible, and work done the inventor retreated to the shade.
He watched the other island for some time, still chewing on carrots, until his usual lack of boredom tolerance set in. He figured it would be a while till somebody made a bonfire over there anyway, it had taken him the better part of the morning.
He turned and walked into the woods, looking around, picking a few of the fruits and examining the plants. It was hard to tell what could be poisoness here, but he didn't think the aliens would poison them all immediately. There had to be more informative ways of killing them all for their experiment.
All in all this place seemed to be a paradise. Similar to several of Isaac's favorite holiday vacation spots.
"Only one thing missing, really," the kid said, squinting at a fruit he didn't recognize, picking it and taking a bite. He made a face and spat it out, tossing the rejected fruit over his shoulder. "C'mon. Something here has to be boozeable."
He still had priorities, after all.
