@joda, have you read the books?
Yes. I have other issues with those scenes from a book to TV sense. But I'm alright with those. What bothered me is that is that it wasn't a very well thought out plot line.
I'm speculating that a certain mysterious character from the books, who has yet to appear in the show, is going to show up at Craster's Keep before Jon gets a chance to see Bran. I don't see another option without completely veering off from the story line.
I'm interested to see what they are doing with Locke. The book character he is largely based on (Vargo Hoat) never made it north of Harrenhal and I can't think of another role that they would be combining it with.
