You call her.

The next day you mull on it. You're not sure you like the idea but it's better than calling Anna. Besides, Jennifer was always nice to you in school, she's probably not willing to take it too far, she probably just wanted to be sure you'd help her and is a little desperate.

You work up the will and decide to call her.

"Glad you finally came around to my little idea. Haha. Meet me at 10:30 tonight, I'll text you the address."

You think it's odd to meet at such a late time, but whatever. You head out that night and punch in the address without looking at the map to see where you're going.
