Oh yes ! Just to give an exemple : we have now to re-read Dolorous Edd interventions, with Eddard Stark spirit. That's make them even more funny... and very less gratuitous  Dolorous Edd appears for the first time after Eddard's death, when the NW is beyond the Wall (he is never mentioned in AGOT, even if he is Mormont's squire like Jon and it could be logical to see him when Jon take his functions). His first words :  That why Eddard don't want a grave, surely ^^
