Chapter 21

Chapter 21, called "The Sound of Your Voice" is the fourth chapter of Arc 2 of Exit/Corners.

Synopsis
After suddenly receiving a message at the end of the previous chapter, Ink discovers that Sent has hijacked his Gemini and wants to communicate with him in private. He offers various kinds of help like puzzle solutions or a map of the hotel to Ink, who refuses, thinking Sent is just trying to fool him. He rejoins the Blue Door team, solves the puzzle, then spends some time resting a bit with Rae and Beth. Rae abruptly has an attack of the "Exit/Corners bug", and as soon as Beth leads him out into the hallway to find a bed, Ink hears what seems to be the player's voice, and becomes sick himself. He again has the vision of a thread becoming larger and threatening to tear open the world while the room itself churns around him, but the vision soon goes away, and Ink and Beth decide it was a mistake to split up. Ink decides to head back to the Black Door team in order to confront Liza with her secret once and for all and convince Sean and Tiana to join up with the others in the Blue Wing.
