I noticed when grinding out expeditions that certain characters seem to like very specific events. While getting an event always increases support points no matter which option you choose, some responses produce flashy sparkles on the screen that I only assume means that they like that response more. I went and tried both responses for characters, but it seems that only one response on one event produces sparkles. I want to know which event and which response produces sparkles for each character.
Since this is a pretty large undertaking for me alone, I'm opening this up to other people to help fill stuff out. For now I'm leaving this on "comment mode" only to promote discussion in this thread rather than people just slinking into the spreadsheet, making edits, and then no discussion happens in the thread. To start off, I know that Seteth and Linhardt like fishing at the waterfront, and Lysithea likes playing in the water at the waterfront (to her own chagrin). https://docs.google.com/spreadsheets/d/1Wsa6GNW3pgvKVoduZ7r-5yBoeAqh91JL4nx6QmZDGcE/edit?usp=sharing
Here's what the sparkles should look like. Happy hunting.
Edit: All the choices got datamined and are listed here. Have fun looking them through! As of the time of posting the full responses are not recorded yet but they'll be there in the probably not so distant future.
