Why in the following sentences we omit articles (I'm basing on what I've heard in Game of Thrones - episode 1, season 5):
- You will be queen!
- You will be king one day!
I would say "a king" and "a queen". So should I also apply the same to other nouns like politician, programmer, boss, pope e.t.c. and also say "You will be politician" instead of "You will be a politician"?
And what's more interesting, in the same episode, a few minutes later there was said:
- I'm not a politician. I'm a queen.
I'm really confused about it.
