@Zar:
That's probably it, which disappoints me a little. Asking a life threatening question makes me assume the choices matter. But Mama might as well have said "Fish or Chips" to Jinbe in a very terrifying voice and nothing would've changed. What is even the point of answering? If Jimbei had just walked away without fear would nothing have happened?
She is asking actual questions and the choices do matter. When she said "Life or Treat" to Moscato and "Life or Cake" to her cooks, they had the option of satiating her with food. However, in both instances they were unable to give her the second option, so the first option is what they ended up with since it was the only possible one. Jinbe walking away would have had the same effect as what happened last chapter, but it really drives his bravery home that he was willing to answer the question and accept the option that no one ever accepts by choice.
@Tamiel:
The first page and half is something I really do not like, but seems necessary considering how many people need to be told explicitely everything. Many knew that Capone had ordered his men to place mirrors inside the wedding cake, was seeing this flashback needed?
A little explanation is better than none, because in my experience as an OP fan, not everyone is as capable of connecting the dots as others are. Plus, this is riding on a plot point that happened nearly 30 chapters ago, so I'd say this was definitely necessary for the average fan.
