Im living in the Netherlands and we are seeing episodes from February 2006, and in the last episode Nancy was on and she had scenes with Katie. And I just remember that most of the Scenes Nancy has are with Katie (in 2006, and now in America). Can they only use Nancy with Katie?

Apparently, yes. This is the only use TPTB have had for Katie since February 2006, which you're currently seeing. After a long absence, Nancy returned a couple weeks ago. I don't have to tell you who her scenes were with. Goutman should have a whack upside the head for this. Helen Wagner is PAST the age of life expectancy, and yet still willing to work! But instead of making her final contributions to the show as the Hughes matriarch she's been for decades, that part of her character has no place in Passanante's Oakdale.
