I don't want to see Lola is the daughter of Big Mom. Just because Lola said her mom is famous, powerful, ect, doesn't mean it HAS to be an yonkou. Whitebeard had brought 43 allied captains from the New World who were famous. So Lola's mom can still be a famous pirate and not be Big Mom.
I'd love to see more female captains so thats why I want Lola's mom to be someone we've nto seen yet.
