"Do you have to have, like, a bond with the person you're doing this with, or can it be anybody?" Jim asks curiously.

Faris moves a little on Hunter's skin, shifting position so that he can peer out of Hunter's neckline. "A bond is preferred, but not necessary. Not all species can serve as hosts, but humans seem to be perfectly suitable for K'da. I must return to this state at least every six of your hours, or else I will perish."

Jim files that away under important things to know. If something happens and they get separated for some reason, it's a comfort to know that Faris won't be totally screwed.
