Throughout Days 12-13, there are multiple Paige Codes that can be discovered/unlocked - these are then input in that ? on the Laptop.
One is found in the Escape Room, another within the Laptop bio page section during Day 13, and the last is found within Day 13 itself, early before the laptop session begins. These codes unlock bonus pictures for the laptop album section. More will be added to this with each update.
I appreciate the compliments about the spelling/grammar. Glad you're enjoying the game!
