So I was doing some exploring just outside of Riften. I happened to be wearing the Mask of Clavicus Vile while swimming across a lake when I heard the voice of Barbas say "Why do you keep following me?" or something like that. I do not have Barbas as a follower. Has anyone had this happen to them? I'm not sure if there's any relation to wearing the mask and hearing the voice. I tried looking into this but couldn't find any info.
