It's all practice for my future career as a femme fatale. [Said with only a hint of a smile as she teases Kurt. Then he makes his guess, and her grin widens as she glances up at the umbrella.]

Congratulations. You've avoided one shopping trip. At least for now. [But if he is going to play tour guide, Zatanna won't leave him to get drenched in the rain. So she lifts a hand toward the umbrella.] Ekam siht na allerbmu rof owt!

[There's no smoke this time, but a visible transition as the umbrella grows in size until it's large enough to cover them both. The effect doesn't take long to complete, and she shifts the umbrella so it's over each of them.]

I'm Zatanna. Nice to meet you.
