Arya, Bran, and Jon? Which is the emotional one, and which wouldn't make you unhappy?
For me, it's kind of the inverse. I've grown *more* attached to a broader range of characters as the series progressed. Jaime gets all sympathetic in aSoS, Sansa gets tolerable after leaving King's Landing and starting to legitimately be able to see the world beneath the shine of her bard's tales, the wildlings get humanized quite a bit with Jon's interactions with them, Thoros does a lot to redeem the Lord of Light from Mellisandre's creepiness and ruthlessness, Arya gets harder and harder to let go; I want her to totally get turned into a girl with awesome assassin skills and then get reunited with Nymoria, if anything happens to Bryndon I'll be royally pissed, the Hound has been made a lot more sympathetic, too, Tyrion ends up getting a lot of pathos and trying to do the right thing while not getting devoured by his family, I've already ended up feeling just ultimately sorry for Theon, for how much he's **** things up, while Asha ends up just being a cool little spitfire who I can't bring myself to wish ill upon...
About the only characters who I'm really actively rooting for to die in a fire are Cersei, Joff, and maybe Tywin (though, Tywin doesn't have to die -- I'd settle for his ambition ripping his family and lineage/legacy to shreds in the ultimate schadenfreude). I suppose ultimately, my biggest wishes are still for the Starks to come out okay after all this. But there's a lot of folks that I don't want to get trampled on along the way, even if that's still the end result. Which is perfect for GRRM, as that means he gets to crush my soul again and again, still.
