Kate thinks Bruce is being ridiculous. She's not in love with you, and nothing he says will convince her otherwise. Something he does, on the other hand...

Bruce pushes Kate onto the dance floor, right into your arms. Her eyes widen as your hands land on her shoulders, and her hands land on your waist. Kate's trying so, so hard not to kiss you right now. It would be so easy. It would be so perfect!

But she pushes the thought out of her mind. She doesn't like you like that. That's just absurd. Kate simply does not feel human emotion, especially not love. And definitely not for you.
