Simon had been laying in the maintenance shaft for quite a while now, over top of everyone in the main portion of the ship, just watching his teammates. While they do all seem a little crazy or antisocial, they all seem capable enough to at least not get him killed. It remains to be seen how they work together as a team, but that really wasn't his problem to worry about.
What was his problem, was the fact that the guy in the weird suit just made his way to the cargo bay, cutting off the only stealthy exit from the maintenance shaft. He could still get down, but it would put him right in the middle of everybody and that was the last thing he wanted. That escape plan was reserved for emergencies.
"I guess I have a lot more waiting to do," Simon thought, trying to get comfortable in the maintenance shaft, and missing the cool, dark comfort of the cargo bay.
