Guys, I just had a revelation!!! I have just thought of the most plausible theory as of yet!!!!

What if the vivre card from Lola in Thriller Bark is from Big Mom the Yonko, and then Nami shows Big Mom the vivre card when Luffy and her are fighting, then Big Mom will forgive Luffy and the Strawhats because she has a connection with them, aka lola

I know this isn't well thought through but I hope you guys like this ORIGINAL NEW theory that I CAME UP WITH
