Dana Winters is a former agent of Division that first appeared in the episode Glass Houses. Nikita plans on killing her to recover one of Percy's black boxes, but instead saw that she had forsaken Division to start a relationship with a man outside Division and his son from a former marriage. To gain information, Nikita and Michael pose as newlyweds that have just moved in around the corner. When Dana is confronted, she tells Nikita that she has stopped being a Guardian of the black box as to lead a safer life with her partner and step-son.
Percy says in "Pandora" that he made a deal with Dana that, if she aided him in his fight against Nikita, he would allow her to live a life with her husband and stepson, although it is ambiguous if this is true.
