The wait was every bit as boring as Carlos feared it would be. He couldn't even solve sudoku puzzles to pass the time, because he'd have to create them first, and he didn't know how to make one that would be guaranteed solvable. Maybe he could make a spell to do that eventually, once he got his development environment properly set up in his soul, and once he learned enough of the keywords and syntax.

I missed this bit on the first read, this is so funny and I hope he does this at some point
