I think the alpha can mark an omega but the omega has to think about that person that marked him because if he don't the mark would disappear. In kiss me liar the omega had memory loss because he fell from the stairs and he lost the mark but later he got it back when he remember everything.
Oh it's not the same as kiss me liar when chase said that only omega can mark an alpha but alpha can mark an omega? Sorry if I'm mistaken
