Morag... hmmm. I'd be way out of my depth trying to sum up anything of her character from the early years, so I'll just focus on what I know.   She's not technically main cast, but she commands so much respect that no one bats an eyelid when she takes focus for weeks at a time. But I don't think anyone would really want her to be main cast. There would be something wrong about tying a character like Morag down. Which is why I don't particularly like her being lumped with a dead weight like Ross
