SUPERGIRL QUESTIONS

Ugh. I just have so many questions.
  1. Are we in the same cannon as Man of Steel?
  2. Are we going to talk about Superman V Batman when that happens?
  3. How about Arrow?
  4. And The Flash?
  5. How can she afford that apartment?
  6. Does personal assistant to a media mogul pay that well?
  7. Did mom and dad El leave her with a secret bank vault of money that can only be reached by Goblin?
  8. National City
  9. Starling/Star City
  10. Central City
  11. Metropolis City?
    I guess "City" City was one step too far on the redundancy scale.
