I was thinking about a universe where superheroes were already established, which could be a problem given possible movies unless it works with them. 'Smallville' was what it was and Clark didn't find out about other heroes until like S9 and then we didn't get a Conner until S10. Clark had his little group in S6 and on but it wasn't like what he discovered later on in S9. I really don't think it has to be like 'Smallville'. 'Arrow' seems like leaps and bounds a head of it half way through the first season.
