Yeah... =/ I started listing all these reasons Sansa and Sandor may be together in the end (she has a thing for knights, the relevance of the song, etc etc etc) to a friend of mine and he started laughing, and goes "the very fact that you CAN make that comparison means he's planning something horrible for them."
My heart just melts at this and then it aches because George R. R. Martin is cruel and people are never too happy in the actual story. Thank goodness for fan art.
I love the display of personality in each of them. Sansa would clearly be a doting wife and mother (she still seems rather idealistic, even if experience has jaded her a bit). Sandor is restrained with his emotions; he's not grinning, but his eyes and posture say he's happy with his life. The wide-eyed innocent daughter is just precious.
