Dany won't die in Essos. She's going to reach the Trident according to prophesy, and likely the Wall too.
I liked Tyrion's ADWD chapters. People expected him to return to being a witty dwarf immediately but he was in a very dark place mentally after ASOS, and his drunken ugly state of mind was fascinating to me. I'm in the minority but I really liked Penny, largely because she brought Tyrion back to life. It was interesting seeing how disgusted he was at her slave mentality, and it's one of the things that convinced him not to drink himself to death.
I didn't expect him to die when he fell in the water but I thought he'd get greyscale for sure. He might have it internally. Also I liked how he sniffed out Aegon and so easily manipulated the so called perfect prince. Varys seems to have created a smart but very arrogant and brash king.
PD,
I'm gonna talk to GRMM and see about getting you on as his editor. You seem to have good insight into the series as a whole.
