User blog comment:Fliu/Should Lola have told the Straw Hats who her mother was back at Thriller Bark?/@comment-26058050-20170419075210

I think the idea of Lola talking about her mum without actually saying who she really is, is all part of Oda forshadowing Big Mom's character, and then later linking them back together. It's just a method of spoilers but doing it in a subtle way that the reader doesn't pay much attention to it at the time.

It's also a possibility that Lola describing her mum in that way is her way of coping with what she had done to her family, and would rather think of all the good things that happened to her (if any).
