- 1:05Day[9] enters the underground tunnels through the toolshed, retracing his route toward the Reservoir.

The key gets forgotten. Sean "Day[9]" Plott retrieves the Sanctum Key underground, heads upstairs, then realizes that talking has distracted him from actually putting it in the door.
It is a fitting little moment in "This Crack Looks Familiar" - Blue Prince | Day9, his first of two uploads this week. Plott says he is easing back into streaming after a difficult few weeks away. Blue Prince supplies a familiar occupation: retracing tunnels, checking clues and finding yet more things to investigate.
The session has reached roughly 21,000 views, making it the most watched of the week's new uploads. Along the way, he combines a shovel and metal detector into a detector shovel, laughs at a chat question about whether he is live, and turns a movie guessing game into a discussion of Margin Call and the financial crisis. Puzzle-solving leaves plenty of room for conversation, even when the conversation interrupts the puzzle-solving.
Viewers are discussing how far his no-notes approach can take him, remembering the satisfaction of filling out the house and recognizing the game's habit of rewarding a solved puzzle with another puzzle.
"Where Are All the Letters? - Blue Prince | Day9" followed the next day and is now bringing in the most daily views. Both sessions are considerably more active than October's Jonathan Blow preview, which continues to attract a smaller trickle of viewing.
Across the channel, weekly views came to about 102,000, while subscribers slipped slightly. Daily viewing is a little below its usual level. Among nearby variety-gaming channels, Lazy Mattman had a much busier viewing week; Day9TV's return was a smaller affair, centered squarely on Mount Holly's unfinished business.

Where next?
What viewers say
I think we have reached the point in the game where the feasibility of his no-notes style is really going to be put to the test hahaha.
