In such a fanfiction, it could be a really heartwarming story. Maybe Terry finally decides to put his dangerous Batman life aside a bit more for Dana.

Catwoman, who has always loved Batman but was afraid of commitment, finally says yes, seeing that he is truly committed to her.

Batman, on the other hand, might start to notice some changes in her behavior and become suspicious.
