I also watched it and thought...I don't remember this in the books. As to why change a good story I don't know, unless they are trying to make Dany's storyline more interesting to the viewer. I did find her chapters a bit boring, but there are others who love the Dany/Dothraki storyline. I think when it comes to the bastards in the book, the author is only following past history when being illegitimate was a stigma...But in the end one feels a comraderie with these characters Aka Jon Snow and Gendry and you just long for them to succeed.
Madeleine: They've also altered some of Jaime's scenes too...I enjoyed his scenes and it was nice, in a weird way....I noticed they've also altered the Theon/Bran/Rickon storyline....
Now there is a character who I wouldn't miss if the producers decided to kill him off. I find Theon totally boring as well as the whole Greygrims

Also I was surprised by Ygritte clean look. I was expecting someone with wild hair and perhaps a more feral type behaviour...Osha is definately more wild looking.
Sometimes I don't know why producers make changes when the storyline is good anyway. It was the same with the Tudors, they changed so many things when the facts are more interesting than the make believe.
Oh well...I just hope they leave...TYRION ALONE!
