Wei Wuxian has quick reflexes and he starts to strike out against the one who grabbed him when he stops himself. He has been around Lan Wangji enough to be able to tell when the other is close by. He can smell the slight scent of sandlewood and the way the wrist was grabbed is not out of malice. "Lan Zhan?"

He obviously can't be certain with his eyes the way they are but there really isn't any reason to strike out even if it isn't the other man. As far as he knows no one in this hotel really wants to cause them harm. So he relaxes and turns a little, reaching out to see if he can feel the familiar robes of the other man.
