This question contains spoilers… (view spoiler)[Asking to see if anyone else noticed this. In Ch. 23-24, after the 2nd duels the 6th, the 3rd steps forward in challenge. There's arguing from the 9th & the 4th, & the 3rd steps down. The 8th & the 2nd leave the room, and then the text says, "The three Houses left", but I counted 4 Houses still present.

At some point the 3rd left the room, but it's never explicit. Anyone else notice this or were confused by it? (hide spoiler)]
