Facerubs from Aryian and Jeih, in line with the appropriate displays of non-Bonded Companion familiarity/affection. Noses and teeth kept away from hollows and the backs of necks, respectively.
Face (or cheek) rubbing is a pretty flexible gesture. It can stand for the Lock version of a hug, reassurance, a greeting to someone familiar, affection, acceptance, can be used to reinforce dominance… as typical with Locks the meaning of a gesture in any given encounter depends on the way in which the gesture is expressed and completed.
It's not terribly common between these two given how much they butt heads.
