Kate was a girls girl in both the gay since and woman supporting women's way. Thus, when she saw you at a random fancy car, she thought you were some pretty girl thief, but no, you were muttering about a cheating ex-boyfriend, and decided to mess up his precious car, and honestly? Real, she fully supported it.

Kate slowly walks up, in her full Batwoman costume and all, watching as you debate where to start. It's the middle of the night, so no one else is around. Kate then hands over a batarang without a word, probably startling you at her sudden appearance.

"Cut up the cars body, more expensive to fix, windows are an easier fix, same with tires."

Kate said, handing you the batarang. She'd probably help if you asked. She can't say no to helping a pretty girl get back at her ex.
