I enjoyed how you had Spencer keeping a journal written in some type of cypher. The delivery of the books was creepy, as you intended. I totally believe that the team really doesn't follow the rules when it comes to their own safety, and I like how you make that point. That what Spencer "should have done" is something that he doesn't do (going to the police or the Team). And the glimpses of the pre-S7 team is nicely done as well (although I was kind of hoping for a reference to Seaver).

The details about the handwriting and the tone were superb!

Overall, very nicely done. Thanks so much for sharing.
