Honestly Howard Gordon and Alex Gansa had a major problem writing good portrayals of teenage girls. Witness Kim Bauer after Season 1 of 24. Dana Brody was interesting in Season 1, but after that the writers completely destroyed any real character she might have had. A lot of people don’t like Season 2 of Homeland entirely because of Dana’s storyline and while I don’t hold with that, I can understand why they’d think that way. It’s why i consider Season 3 of the series the weakest and why I think the series got better when it abandoned the Brody’s after that year.
