César lets out a short laugh, because he's also forgotten to introduce himself, and his mood bubbles up to something warmer. "César Salazar. Honestly, I can only hypothesize instead of theorize, but I am enjoying that." They just don't have enough information to make anything a proper theory, and yes, César is pedantic like that.

"Speaking of, all of those are good hypotheses. He might just also be strange enough that he collects dirt for his... potted plants this way? Or maybe he's cursed in such a way that forces him to gather dirt in this fashion. Or perhaps he's a humanized dirt pile that needs to continue to collect more dirt to keep his form together?"

None of this will get them closer to the truth, but it's a good brain exercise! César likes those!
