She really is, but I enjoy loathing her. I especially enjoyed watching her destroy herself.

Arya left him to die? Supposedly some monks at a monastery found him and buried him, but all the monk would say was that 'The Hound is dead,' he never called Sandor by name. While they characters are talking about this, though, there's like a cowled monk mentioned in the background that walks with a limp like he's recovering from an injury and has an affinity for dogs, so...fingers crossed!
