There was a difference between being on a ship where you belonged and a ship where you were a passenger. For starters, when you were a passenger, you tended to get treated like cattle. Less so much on smaller vessels, but on passenger liners you had a two meter by one meter space to call your own and it was to Astor's displeasure that this was their accommodation situation for most of the two-week trip to Gaia.
He didn't do too well in enclosed spaces. He didn't like sitting still. Chess told him to read, but comic books were only interesting for so long. Astor tried to go exploring, but he only got down a deck or two before someone found him and yelled at him. Furthermore, he suspected that he was in more trouble now than he would have been if he were a child.
Chess, at her wits end, gave him a small tablet that looked suspiciously like a decongestant and told him to go sleep for a while. (This was mostly to get him out of her hair.) Begrudgingly, but not wanting to anger her further, Astor downed it and sulked away into his very small sleeping quarters. The pill was fast-acting, so thankfully he only had to deal with a few minute's claustrophobia before he drifted off to sleep.
