Very nicely done. The only thing missing is why Harry isn't nervous about where he will go after leaving Enterprise. Other than that Cateagle said it all.

Harry's had 6 weeks aboard the Enterprise and in that time he's been about to find out that the federation makes sure that Orphaned kids are taken care of properly with education and a proper home to live until the age of majority. So while it will be different for him as far as he knows its going to a million times better than the Dursleys
