Onion Ring Knight replied to Hmadkour's topic in The Winds of WinterWell, Thoros did manage to fuse various of Lord Beric's body parts back together, close holes in his flesh from lances and swords, etc. It just worked a little less well each time, and worked as well as it did because he was "freshly dead." Cat's corpse was three days gone and waterlogged before she was raised.
Onion Ring Knight replied to Hmadkour's topic in The Winds of WinterI don't think he is "definitely" anything, let alone a "legitimate human being" after Qyburn's work in the black cells. Heck, he may not even have a head inside that helmet! I've read DANCE twice and never gotten that impression at all. Time will tell on both of your assertions but they're certainly not givens.
