Yeah, I'm pretty sure that's what happened.
But it's interesting that this is the first season that this happened. Did the doctors decide this year that caffeine supplements were no longer okay? Or is it just that she gave them to the contestants without asking the doctors first? It seemed kind of odd. Though the good thing is that Jillian's team would have lost anyway, without the four pound penalty. But if they were voiding the last week's weigh-in, should they have brought Ruben back to weigh in again???
