Who was the Queen of Thorns betrothed to? Her age is kind of indeterminate, but if she's 85, I figure it could be Aerion Targaryen himself. Her comment about him is what makes me think that. On the other hand, if she's younger, I suppose it was one of Egg's sons.
She's not that old. Remember, she's Mace Tyrell's mother, not his grandmother. She's in her sixties, I'd say. Did I say she was older in the manuscript? If so, I need to go back and fix that. As to her betrothal... that's a story yet to be told.
"A fanfare of trumpets greeted each of the heroes as he stepped between the great oaken doors. Heralds cried his name and deeds for all to hear..."
The Tyrells are given pride of place. Are the heralds recounting deeds on the battlefield of the Blackwater or something more general ('knighted at 15, defeated the Kingslayer in the final tilt on Joffrey's nameday, etc.')? This has to do with the whole Renly's ghost thing, I admit, but if Loras and Garlan both have an arm-long list of deeds from the battle recited as they enter the hall...
The Knight of Flowers fought gloriously on the Blackwater, and I have no doubt that the heralds mentioned that, but his other martial accompishments were also mentioned, no doubt.
