Book readers: The show has not delved into the subject of Jon Snow's parentage quite as much as the books. Spoiler Including Jakerock's line about Ned never having claimed Jon as his son. jakerock, that line is from the book only. Refer to the 1st season 2nd episode where Ned in fact refers to Jon as being his son. Let's be very careful about bringing a topic that has been discussed at length outside of the TV show to the TV show thread.
