Did the actor for Dario (or however you spell his name)? He looked different but I haven't gone into IMBD to check this out. I liked last years version better.
I've only read up to Storm of Swords (I think that's the title of book 3) so I'm trying to remember what's happened and I know they may be starting to merge different ideas from the books as they weave in and out. So a few questions which for people that have read further ahead (or just have a better memory than me!)
Are the events of Dany's current storyline covered elsewhere? I don't recall much more from her storyline other than the conquering of the current city (which happened last season)
Yeah, they did change the actor for Dario Nahaaris. He's now being played by Dutch actor Michel Huisman. If you watched the HBO series Treme you might recognize him.
Dany is continuing on her travels through Slaver's Bay. Last season she started in Astapor. That's where she got her army of Unsullied. She took Astapor when she freed the Unsullied, and then they took Yunkai at the end of last season. This season Danaerys and her army are on the road from Yunkai to Meereen. I'll leave it at that so as to avoid spoilers.
I was pleasantly surprised with the first appearance of Prince Oberyn of Dorne. I was genuinely wondering how they were going to handle the Dornish since they really haven't been seen in the series up until now. Culturally, they seem to be a blend of Spaniards and Arabs, which is somewhat in line with George RR Martin's vision for them. As for Oberyn? You've got to appreciate someone who's willing to show such outright hostility for the Lannisters in Kings Landing. Everyone else that opposes them has done so in a very covert, measured way. But sing "The Rains of Castamere" in a brothel and that's going to buy you a dagger through the wrist, courtesy of the Red Viper!
And speaking of "The Rains of Castamere", word has it that the Icelandic band Sigur Ros will be making a cameo, playing the House Lannister song at some point this season. I get the sense that it might be happening on this coming Sunday's episode.
