"I'm pretty sure thieves don't have rules. That's why you're thieves!" He stomps off to check on his room, but the door is still locked, and everything inside looks in order. Time to retrace his steps to find out what could have happened. He did have the journal with him earlier, as he was writing outside by himself...

As he does so, he yells to Tina again. "I'll have you know that keeping a detailed history is important. Just because I'm in some other world doesn't mean I don't have to record it. But unless I say so, it's not open for reading!"

Mostly due to the fact that a lot of it wasn't history, but his opinions on not just the people he's met, but on Aqures Ixen itself, as well as some of his future plans for the military. Written in a journal like this, it seems like nothing more than daydreams, but he seems pretty serious about it.
