Wanda has always respected Parson's tactical mind. The two have a good working relationship, but Parson fears her and considers her a monster.
However, in one case, she has chosen not to follow his advice. Wanda sees Parson as another agent of Fate, and believes she knows his future well enough to be able to predict that he will suffer and take losses in future battles.
Wanda has willingly shared some of her secrets with Parson. She does not seem concerned that he might ever use any of them against her.
