Looks like there's a fair bit of feuding within Big Mom's family, seeing as how Praline and Chiffon are allied with Capone.
The part regarding Big Mom's history with Elbaf was fairly interesting. The fact they were feuding before the marriage arrangement says a lot for their history. It also helps hype up Elbaf, since it's status as the world's strongest nation and the implication it could avoid being subjugated by a Yonko suggests that most of the characters relevant in the Elbaf Arc could easily be Yonko Commander tier, with the best of Elbaf probably being Admiral/Yonko tier. I'm guessing from even Lola refusing to marry Loki, he's being set up as a nefarious character that could most likely be the antagonist of the Elbaf Arc. His name's connotation with trickery also implies that much like Wano likely being Zoro's spotlight arc, Usopp may actually be the MVP of the Elbaf Arc. Pretty nice foreshadowing/build up overall.
