[He got the note from the Usyagi about where he and Aramis are going to be staying and so he's there checking it out. He's familiar enough with the forest huts - certainly remembers from when Aramis stayed in one on his own all that time ago - but he wants to at least get a sense of things first... and see if all of Aramis' stupid pillows stuck around.
He's curious about what's still around, too, so he'll be making the rounds. He's starting at the library (because of course he is) and while it all seems the same at first, it doesn't take long for him to find the rows and rows of old journals. And, well... it's strange that it feels so unsettling to see them all like that.]
