I wanna talk about tashigi .. she is weak .actually i would have hoped she got a lot stronger.
Now she is beaten by law and vergo... okay i know she got beated by top dogs.
but she couldn't even defend herself...so hopless.
So that's why i think she will eat that DF.

About the dragon...
it's stronger and more developed then the previous one
but honestly, it shouldn't be a problem for zoro and kinemon or brook

Other thing is where is frankyyyyyyyyyyy suuuppppper.
i think he coated the ship or is planning the escape
but in order to do that he must already passed the the doorR66 or some like that
