Prediction: Pippa wastes time and teases for 3 hours and then flashes a millimeter of ankle for one second at the very end.
At least that's what I hope. That way she can technically keep her promise without encouraging the pod people to remain in her audience.
On the other hand, to be frank I think she likes this kind of attention. I've seen her put it on blast multiple times, including reading the entire "I want Pippa to make me come with her feet" post on stream.
So... we'll see. Almost time for the "feet"-ture presentation.
