BTW, it's quiet possible Luffy's and Nami's reaction were NOT I repeat *NOT* about the Yonko's name. It seems like Law told them his basic plan while they were listening - THEN Nami's and Luffy's reactions make sense.

Luffy then agrees to the plan "...oh, alright" while Nami is shocked. It all sorts itself out, the Yonko is BM and they're probably gonna join forces with Kid, this way they'll stand a chance against the Yonko.

All I'm saying is that it's possible, an option most people didn't consider.
