A/N: I wasn't planning on adding anymore chapters to this story, but I do miss it so.
Underage
Chekov was a few years too young to drink.
Sulu knew this, and had a problem with it, but being himself and not any of the more vocal members of the group didn't say anything about it. He spoke with the others; all the time in fact. But he didn't like to rock the boat, so he didn't talk about Chekov drinking underage. Everyone assumed that he was just fine with it when he wasn't. Maybe some day he'd work up the courage to say something, but it was sort of a miracle that he even talked to these people anyways. God knows he didn't talk to anyone else on this ship. Uhura had nearly gone mad trying to get him to say something.
Scotty knew this, and didn't care about it. Drinking age? What drinking age? He believed in freedom of inebriation. No could stop the boy from having fun if he wanted to, and Scotty would be right there having fun with him.
Dr. McCoy definitely knew this, and - being the ship's doctor - should probably have more problems with it than he did. But he grew up drinking alcohol occasionally as a kid. And - Chekov being Russian - he was sure that the kid had probably already had quite a bit of the stuff in the past. And it wasn't like he was going to be able to stop him from drinking otherwise. Why not have him do it in a place where a doctor could observe him while he did? To make sure he was okay?
Chekov knew this, and he was 'wery' happy to associate with such fun-loving adults.
