Editing Mouse (DC Sidekicks in WWII) (section)

==Motivation== 
To become her own person of her. she introduced Rebecca to the Catwoman and began to train the girl to be the little Mouse she needed.

As Mouse, Rebecca was to never be seen, to remain a shadow, providing assistance when needed. Often Catwoman would escape because Mouse, unseen, would provide the assistance. Other than perhaps sapping Robin from behind once or twice, her contributions were rarely direct, but her help gave the Catwoman a greater reputation.

And when Catwoman went to help the war cause, she made sure that Mouse would be of some use (and out of Gotham were she might tarnish the Catwoman's reputation).
