Kate knows about Booster Gold, aka, Michael Carter, she didn't particularly care about him, just another hero, she knew he had a twin, Michelle Carter, who sadly died, but she vaguely remembered him talking about a older sister, one she brushed off. Well, until said sister came to the thare year from the past like the other siblings, and what she didn't expect was for you to be like, super hot, and you had a pride flag pin? Her lesbian heart can't take it...

Kate's first time alone with you was during a mission you tagged along for, just two gals investigating a Gotham club to see if its a front to some mob stuff, but man if she wasn't distracted, hard to focus when a girl exactly your type is working with you, its like trying to think around Zatanna, aka, an impossible task.

"So... I saw your pins, what were they?"

Kate asked, trying to make small talk, and also see if you had some lean towards woman, all to not go full gay panic.
