Delightful parts. Clark slowly coming around to the idea of a public persona is very well done.
So stock costume or one with a mask?
There was a fanfic I read years ago where Clark wore a costume with a mask and later publicly removed it.
I don't recall if it was here of fanfiction.net or if it was L&C or movieVerse or Smallvile. I know I read it years prior to Smallville doing their RedBlueBlur comes out as Superman bit.
Of course in the comics and the MovieVerse Clark Kent is always the embodiment of 2 Corinthians 10:10
...For they say: “His letters are weighty and forceful, but his presence in person is weak and his speech contemptible....
so much less likely to be outed as Superman because people are simply unable to wrap their mind around the idea of
that person as being someone let alone Superman.
Anyways enjoying this tale. Looking forward to more.
