Once her bank accounts were up in the millions, she decided to treat herself. Spa treatments, shopping trips, and so on. Once she was sure she was at her best, she deicded to make her move. To get the partner she wanted, no, deserved. Which was why she was in her costume, even with her make over. Since the best way to get Spider-man's attention is to be at the scene of a crime. The question was... to show up as the bad girl criminal who needs to be punishment or to get someone else to rob it and appear as a heroine helping him?
'Each has it's pros and cons. If I go as a good girl, even if I cause the robbery, I would get credit for being on the straight and narrow. Which would please Spider. Given him common ground to connect with. To prevent lying, I could skip getting someone else to rob it and instead get someone to tell me their plans ahead of time and forget they told me.
The most honest method would be myself as a sexy naughty lady. Especially since I could give my loot back, talk him around, or use other methods to get forgiveness. I might even get him to agree to keep what I had 'earned' from my labours.' she thought as she debated the path she was going to get her man. Assuming something else didn't appear to her instead.
