@otakufan:
A mirage tempo is perfectly in line with what Nami is already know to be capable of (provided there is an appropriate image nearby that she can use for her purposes - i.e. another burning ship)
Pudding doing some form of memory editing would either require her to be capable of rewriting the memories of hundreds, if not thousands of people at once (i.e. everyone on or near Cacao Island), or that she had spent an unknown amount of time systematically targeting each individual that was present without getting caught and this is all something the BMP are remembering after the fact (which is little different than the "BM's just hallucinating this" argument).
That doesn't sound like an option to me, considering Nami looks scared shitless and the flag is floating in the water.
Of course, the flag might have fallen off on its own, but that would be Kubo level of trolling.
I was more suggesting Pudding managed to alter BM's memory. Maybe, somehow. The option is still in the air in my opinion.
Just like BM's weird hallucination. It's pretty clear she isn't quite "there". Is it an aftereffect of her devil fruit, some inborn defect or a result of a third party devil fruit? Beats me. I have a feeling it might be related to BM's origins and that we were deceived in some way.
Basically, anything would be better than a mirage tempo. Mirage tempo could maybe buy them a minute before they are discovered, otherwise BMP become jobbers once again.
Btw, forgot to mention. Love how Smoothie is now Daifuku's side kick.
