I have recently begun an umpteen playing of DeadFire. When I received the Family Feud quest, I went to Ezzali, asked if she wanted to negotiate, went to the Valeri, and got both of them to agree to terms, which completed the quest. I did not question the fiddling son, pasha (?), the carousing ratouille (?), etc because I never received the Sinking Feeling quest. The only rewards I received were the weapons (Duskfall and Luxury); I never got the sails and hull upgrades.
