Rai ends his speech with his usual smirk. Honestly, it feels more like the words spoke themselves.
Galaxian finally mutters, "...Sorry."
He's not really used to apologizing, unlike GGaD!Galaxian, who apologizes too much for the wrong reasons. 

"Okay," he says with a nod, and then he stops apologizing.
It's unknown what Rai is thinking, but at least we can be sure that he's not exactly holding Galaxian's social skills in the highest regard at the moment.

"Galaxian,,," Rai's actual tone makes it pretty clear that he's using the three commas. 
The forumer looks at him like Rai's the weirdo. 
"I'm not Hitan," the cyber agent states the obvious. "So..." He makes a vague gesture. "You gotta self-regulate."
Galaxian nods like he understands. He does not.

"Yep. He's not doing it, though."
Galaxian tilts his head to one side and then back, seemingly trying to get his gears working again or something. He opens his mouth and then closes it. Oof.

"His manners," Rai explains while Galaxian nods along like a robot. The forumer is fixed with a look and a somewhat sinister smirk before the agent continues, "He's not exactly showcasing the best social etiquette at the moment."

"Alright, but you said it, not me," Rai goes with a humorous smirk and a fingergun. His voice is still monotone, though. 
"He's not coming up with an excuse for himself, so here's me doing the work: He might be slightly tired," he adds, though his tone is now befitting of the way one would verbally say "Press X to Doubt."

"Thank you," Galaxian says in a way that somehow conveys that the thanks is sincere but not sentimental at all. "I don't sleep," he adds, thinking that it's obvious.
Rai looks perplexed in a way that conveys that he likely prefers the company of the tree over the forumer. At least the tree knows how to shield him properly. Now, it's like he needs to be the puppeteer of an oblivious puppet with no manipulable social ability strings in the first place. 

"Do you?" he asks like the incredibly dense (in the head) entity he is. Technically, that's actually the brightest thing he's done in the entire thread.

"You're not doing it," he observes.

"You're sleeping?" he asks. "It doesn't really seem like it."

SLURP SLURP PEBBLE--
Galaxian looks at Rai. "I can't talk to her," he says, all serious. He adds, as explanation: "She's sleepwalking."
Rai just raises an eyebrow briefly. 

"This is a very advanced form of sleepwalking if it is one," Rai points out.
The forumer nods in agreement.
