Merlin smiles pleasantly at Sebastian, as if to say, it's alright, I think you might like this one.

"Son," he says, "This is my friend Asato, of the Ribika folk - like you and I, one of his kind, here. He was in need of shelter."

He smiles a bit.

"Asato, meet Sebastian, who lives here as well and is a dear friend, nigh kin to me."

So, shall we do Merlin-Asato-Seb, in this order? ^^
