"Look here, gramps, I know what you're doing, and I'd appreciate it if you stopped, especially seeing as you aren't any good at it. Seriously, where'd they teach you how to talk to people who you suspect are crazy? Ugh, whatever. I'm out."
John grumbled his way into the hallway and began to make his way back to "his" room to sulk, when suddenly unseen speakers chimed into life. John at once looked up in anger, eyes narrowing as he looked for the intercom he knew must be there. "Zesiro! Doesn't your chicken shit team know not to take away medication from someone who can't tell you what it's for? I mean, what the fuck, man? Did you even bother reading the label before taking my only means of not freaking out when locked up underg- wait." the anger quickly drains away, replaced by a look of extreme concentration, John staring off into the distance.
"Wait. According to the portholes... We... are underwater."
"If the structure collapses... I'd drown... not be buried alive." face meets palm in a loud smack "Ugh, what the fuck, brain?"
"Nevermind, I'm good!" John turns around, rubbing his neck sheepishly as he addresses Vata "Yeah, uh, sorry about before. You know- stress, illogical fear, unfamiliar surroundings, war flashbacks. Other excuses you'll inevitably not accept..."
"...uh, yeah. I'm, uh, gonna go kick myself in the head." he awkwardly finishes before walking off.
