"As a general rule, how much should characters change/grow in a pilot? Slightly, but not much? Unlike that aphorism, “characters don’t change in TV, only in film” — isn’t it true that a character learns something minor in the pilot? That they AREN’T in the same place at the end of the pilot than where they started? And do all of the main characters need to change if it’s a two- or three-hander?"
