Let them think what they want, let them define you in their narrow little minds while they suppress every last piece of them just to keep a friend that never liked them for themselves in the first place.
Looking at Omni-Man vs Supreme -- and how Mark compares to Nolan by the end [I think quite favorably], I'd say this is a good one in the other areas. Maybe? lol
