Aristides was quietly smiling while Futaba started to speak, letting his friend say what seemed to be weighing on him, before they stopped and a different familiar voice made his ears twitch. With widening eyes he looked towards the door and there, sure enough, was Rivers, saying something almost half as stupid as the opener Aristides had used himself. Suddenly the weight on his chest grew heavier. Crap. He didn't know what to do. Did he smile and tell Rivers everything was okay? Did he tell him it hurt that he'd run away from them? Did he draw attention to how long it had been? No, that would be cruel. Still. He had no idea what to say right now. He was already so terrible at talking to other people. This situation called for so much more tact than he possessed.
Futaba moved first, though, and reminded Aristides that sometimes, tact isn't needed.
His expression softened to a weak, worried smile, and he stepped over to the embracing pair that were his friends and placed an arm around Rivers' shoulders and a hand on Futaba's--even with his additional height, the hand was huge--and gave both of them gentle squeezes.

"Hey, don't you go doing that as well. What happened happened to us all. It shouldn't be on one person, or even two people, to take all the blame. That would be a shitty way to be friends. Besides, I bull-rushed that tentacle by myself. Nobody could have prevented that stupid as hell decision, even you, Futaba."
Was this working. Please be working. He was so bad at words, but his voice was calm and tone even. What he was saying--even if he was saying it strange--was still trying to comfort and reassure. God he hoped he was doing it right.

"You two are my closest friends right now. I don't want any more blaming yourselves, or hating yourselves, or...anything like that. We're all adults. At least, I am. We make our own choices. I vote, instead of any of us saying that they need to improve so that...that doesn't happen again, we all agree that dying was an absolutely horrific experience, but that if I wound up doing it again, I wouldn't want to come back to any other people than you two. And we go from there."
He paused, then leaned a little more of his weight onto both of them, so he joined in on the hug.

"I also vote any further discussion be done with something to eat, and drink, and preferably while sitting. You're very dramatic, Futaba. It's as genuinely sweet as it his attention-getting."
