User blog comment:Kaido King of the Beasts/Chapter 872: The Sweet Escape/@comment-24792841-20170714115630

My theory is:

(1) Big Mom ate her entire crew (except, let's say Pudding and Streusen)

(2) When she regained consciousness, she thought every single of her crew left her (like how her 'mother' did, with Streusen being silent and Pudding being too afraid to speak out that fact and with katakuri, being able to foresee, was able to run away to kill the straw hats for 'revenge')

That seems to explain why Katakuri turned out as white as sh** when he forsaw the future chapters ago!!
