'Kay, I'mma thinking of doing this in the same story arc as 'introduction'
Eternity
"Hey, Yao," Xiang placed the book he had been reading on his chest not Twilight, staring at his best friend from where he was lying in the grass until he had the older boy's attention.
"Yes, aru, what is it?" Yao replied absently, flicking a strand of dark brown hair out of his eyes.
"…D'you think, like, eternity exists?" Xiang asked after a pause, glancing away, as though slightly embarrassed by his strange question.
Yao frowned, pushing himself into a sitting position, "Well…" he pondered how to answer such a serious question, "It all depends on what you consider to be eternity, aru. Like, if you're talking about time, I would say yes. Time will always continue, thus making it true- even if there was once a time it didn't exist; if you're talking distance, well, they say that the universe continues forever, thus being 'eternal', aru. Even if it the universe does end, what's stopping it? And what's on the other side of what is stopping it?
They are all… intangible things; they can't be touched, only be seen with the mind, and so cannot be destroyed. Things like… emotions, they are intangible as well, and it's always been a personal belief of mine that 'eternity' exists for emotions as well, they can be passed on, from person to person, affecting generation after generation, and their effects have affect and create more emotion with remanets of the original emotion, th- that's my personal belief, at least, aru." Yao stuttered off, feeling uncomfortable at the intensity of Xiang's gaze, "D-does that answer your question, aru?"
Xiang just cocked his head at Yao, expression unreadable before giving a small half-shrug, "Guess, I, like, wanted to know your opinion on it, that's all."
"Aiyah, okay then." Yao sighed before lying back down on the soft grass beside him, waiting for the bell to ring in about 10 minutes.
