Sam's bedroom was dull and bare. It was clear he just used it as a place to sleep, but Charlie found his real space in the library. He had rearranged some of the bookshelves and made a little study corner for himself with a desk and his own Wi-Fi router. He filled the bookshelves with all his favorite reference books and his go-to translation keys. The larger tables in the library that Sam and Dean shared were strewn with research for whatever current big bad they were chasing, but Sam's own desk was neatly organized with his own personal projects. He was working on three major projects at the moment, cataloging the artifacts from the men of letters, teaching himself Japanese so he could read a book salvaged from Bobby's house, and recording Dean and his own misadventures. Charlie had begged to read Sam's hunting journal when she had figured out what he was doing, but Sam insisted he needed to keep some secrets from her. She supposed that was fair since she had read their entire life stories and Dean had filled her in on the rest.
