Laughs-at-the-Storm definitely approves of Drake's reaction to him, and the following words. Respect for another predator's territory is an excellent notion - understanding territory, and understanding the nature of predators, is rare enough among the residents of Liminal. It works together with the positive notions that he has regarding Drake by virtue of him seeming to be the same species as Gale and Lupa, and his tone is guarded, cautious and attentive, but unmistakably friendly and approving when he responds.

"It is."

In as far as he has a tribe here. ...Actually, phrasing it like that brings up an interesting question. Would Griffon mind the visitors? Probably. Not this specific one, he's sure of that, considering the sense of Wyld that his whole species projects, but all the human and homid visitors... But then, it's just territory. There is no Caern here.

So it should be fine. Or at least not as much of a problem with the humans. Griffon isn't completely unreasonable; the circumstances must be taken into consideration. Strategic tolerance.

"But you are welcome."

There is a very specific you here. Not everyone is strictly welcome. Dragons and other animal companions are, his pack and some people that he considers family are. Everyone else is just tolerated.

"I assume my tribe's markers are different from yours'." Likely more focused on visual things than scent.
