The eighth puzzle begins with Charlie in a red trench coat opening a door to a very dark room. As time went on, the picture changed and uncovered more of what is going on, and may possibly do so again. At the top of the picture are tally marks apparently indicating picture sequence.

In the source of the sixth image is ASCII art of an upside-down Shadow Watcher. In the ASCII of the eleventh image is ASCII of a letter from Charlie. The portrait in the foreground above Maxwell's desk also changes across every picture.
In the source of the seventh image is a box with two arrows pointing to its center, with ASCII art of a puzzle piece beneath it.
