I liked S4 Sam. Like. I really was not annoyed by the demon blood plotline at all! I was like DRINK THAT BLOOD SAM I AM SURE IT WILL HELP, and he was so hopeless I couldn't blame him, and he just--did his best and it was never enough. Uh. Well, I found S1-2 Sam uninteresting and unsympathetic, so?

I like him best when he is trying to run away, and when he fails to run away
HE CAN NEVER LEAVE.

...I would read it anyway. Also have you read this (http://puella-nerdii.dreamwidth.org/110612.html)? It is the Great Dragon trying to make Merlin/Arthur happen.
