Go to the city to fight some crime.

Emma slipped on a pair of boots from Kitty's wardrobe and headed down to the garage. She felt Kitty's car didn't quite match her new look so she "borrowed" Scott's Harley Davidson. After all, Kitty would be getting the blame. She hopped on, revved up the engine, and sped off towards the city.
When she got there she saw Spider-Man, swinging overhead. Most likely heading towards a robbery or something. She considered following him, but she was never really into him. Maybe there was something (or someone) more interesting for her to do in the city.
