Blackie introduced Nancy to Emory Battis while she clung to Jean's side and threatened Emory when Jean requested he bring him Special Agent Dale Cooper. Her and Blackie didn't get a long and she wanted Nancy to go back North, presumably where she hailed from. 
With Jean, she plotted to kill her sister.
She later encountered Dale Cooper, who restrained her and commanded her to take him to Audrey Horne. She did so and drew a knife when he went to the bed. She prepared to stab him, but he subdued her.
