His age is what provides him with wisdom as Onias moves about, curious and unusual - Tesseract can tell immediately that he has stumbled upon somebody less than typical. Yet, it does not feel wholly wrong. The stranger is bizzare, perhaps, but Tesseract was familiar with the bizarre - and the judgement that came along with being as such. And so, he gives little in the way of a reaction even as the stranger leans out to sniff at him despite their distance. Yet he smirks nonetheless when he speaks of his language - old and powerful. Everybody thought that about their own blood. Still, he nods solemnly in respect of it nonetheless. Let him believe it. What harm was there in that?

"At my age, you start looking for things to be curious about," he shrugs in response to the probing question. It is an unusual thing to be asked, after all. Didn't others often like the attention of strangers? "You could have chosen to ignore me too, no?" He raises a brow and saunters forward a step before he sits himself, though not wholly facing the other. He sits as if they are merely occupying the same space rather than giving him his complete attention. "But you didn't. So here we are." He grins to himself before he looks up at the stars, the stranger in his peripherals.

After some moments, he turns half-way to meet the gaze of the stranger again. "You were talking to the stars?" There is a curiosity there that even catches him off guard - why did he care who he was talking to anyway? Something felt off about the stranger though and perhaps the smallest part of Tesseract that sought danger wanted to poke at it just enough to have it show itself.
