Isaac went over to explore the ship. He didn't exactly need to, but standing next to a man who flexes his muscles in his spare time was the less preferable option in this case.

Upon entering the ship, Isaac found that it was a mess. There wasn't that much to see, but there was a ladder which led who knew where, which piqued his curiosity. Isaac went back out of the ship and climbed the roof, trying to see where the tracks led. The mysterious footprints led off east into the distance, and he couldn't see the end of them. But being in a desert like this, they would be swept away eventually.

Isaac got down from the roof. The group was called on to 'investigate' the crash, meaning that they had 2 jobs right now. Finding out what was in the strange craft and finding out what came out of it. It would be a good idea to split up, using their numbers to their advantage. One team would investigate the crash site and the other would investigate the footprints.

There were a lot of unknown factors, however, and splitting up might be a bad idea. The living cactus, for example, was one such unknown variable. How was it alive? How did it live? Might they find more? In that respect, the team going after the tracks might be in more danger, considering that there are more cactuses in the desert, meaning it was possible that there would be more living cactuses. But the fact was, there were no living cactuses until the crash, meaning that the crash might hold some answers. So it actually might be better for all of them to investigate the crash site...

"We should look around in this wrecked... thing." Isaac said aloud, not caring who heard it.
Everyone knew that, but they weren't doing anything yet. If no one headed down, then he'd go first.
