When watching that scene between Johanna and Young Snow, Johanna looks around nervously and then spills the beans about Blue & Eva. Makes you wonder who is sneakier, Blue or Johanna.
That is probably because the Kings men were around and Eva, Johanna didn’t want them to hear. I doubt if Johanna had any other part in what is happening now.
Johanna admitted that SHE wasn’t suppose to know and she looked like a nervous Nellie afraid to get caught. I think Johanna is going to be more important to the story than anyone realizes.
