With the Reeds, i mean, what's the point of adding them at this point then? What explanation will they give for them just showing up? They'll have to make up some convoluted reason for Jojen and Meera Reed - two teenagers, mind you - for travelling all the way from the Neck to Winterfell - now a ruin - and meeting up with Bran and Hodor. In the book, they were wards of Robb at winterfell, and were there before the Greyjoy rebellion and the Bastard of Bolton burning the place down.
