I read an analysis of season 2 explaining why Dana was getting so much screentime. Her subplot with Finn was supposed to parallel Brody/Walden. Both Dana/Brody were profoundly affected by hit-and-run/drone strike. I'm guessing this season Dana will slowly begin to empathize with her father.
Also, two episodes and no Brody? wtf. I'm actually getting bored of Carrie (even though I liked her in the past). At this point I'd rather see Uncle Mike than witness another tired, old, yet another Carrie psycho outburst. Her craziness is starting to wear thin with me.
