It's another hallway, similar to the red hallway. This one is blue, of course, with a bunch of doors leading to some closets and a bunch of other places. Near the end of the hallway seems to be a double-door, but it's locked...and nothing but void looks to be on the other side.
Rue: RANGNGNAGNANGNGGNAGN
Rue, who was simply walking down the hail, is jumpscared by the sight and sound of Dax bursting through the vents. It seems like they're almost genuinely scared for a moment...but anyone would be a bit shocked by something that loud.
"...Why??"
Dax: "Easy transportation," Dax replies, crawling out and onto the hallway floor. "When Gust decided to give us a curfew yesterday, I used those to get a sneaky treat. They can even go from the dorms to the hallways...one way, in that case, but still handy."
Seven Stones: "Hey! Move your ass! There's a bunch more people behind you, Dax!"
Dax: "Mrrp? Oh, whoops."
Dax rolls out of the way, and everyone else starts pouring out.
Rue: With each passing person, Rue grows more and more confused...and disappointed.
"Arsenic? Stranger? Really?"
Arsenic: "Cmon, ya straight-edge...I want at least some whimsy in my life."
Stranger: "I was just curious, honestly. Didn't know the vents were connected like that."
Seven Stones: "...How do you think vents work, Stranger??"
Rue: Blink blink.
"Whatever. I need to go help Tarnish figure out the party's menu for tomorrow."
And so they walk off, unbothered.
Ivan: "So, uh...cool! That was cool," Ivan chirps. "But...seems...dangerous. What if someone uses that to do something sneaky?"
Dax: "Well, I trust none of you to do that. That's why I revealed my tricks...they're special. Very few get access to them, dear."
Stranger: "...Mmm, I guess. Does anyone else know about the vent snooping?"
Dax: "Yup. I've shown almost everyone, save for Gust or that weird green fellow..."
Seven Stones: "I-Is it really 'special, secret tricks' if everyone knows about them?"
Dax: They turn to Seven Stones.
"...Mrrrp."
And they skip away, straight into the cat room~!
Arsenic: "...Man, that guy is weird." Arsenic huffs. "Telling people about secrets like that? Does that guy trust everyone that easily!?"
Seven Stones: He shrugs. "Maybe they just don't care...they have been kinda detached this whole game."
Ivan: "Maybe I should bug him a bit more...see what's up, all of that~!"
Stranger: "Eh, do whatever you want," Stranger says, walking off. "There's a room I wanted to check out, and haven't gotten the chance to yet...anyone been in the art room?"
Arsenic: "Art room? No, I haven't...can I take a moment to look too?"
Stranger: "Go off."
The two of them departed, and Ivan raced into the cat room...leaving Seven Stones alone.
Seven Stones: ...
(...Y'know, maybe I should check on Gust again...)
