I have decided to do this 'by writer-by season'. Meaning -- I will go through the writers of the 1st, 2nd and 3rd seasons and the episodes they've written. Later, I will combine information and thoughts gathered throughout the whole 3 seasons. I might want to wait until season three ends for that, but who knows.
Reason for that structure, mainly, is that this is a team of writers. They work together to develop characters, to accept story lines, to think up new major sub-plots. They also meet before the beginning of a new season to discuss the major themes of the season, together. So really, they all discuss what they bring into their episodes - sometimes there are little details that reflect the person writing it, sometimes there aren't, or not really
So, now we march onward.
