... apparently you have to do a very specific set of choices for the dinner for two one(never got it to proc focusing solely on Marion, but did random picking to get there XD apparently icing out Jessie but picking Grace and Marion options unlocks it), but no specific choice in the portion itself is required(unlock is during the dialogue section starting with 'Jessie loved to see him coming!')
Thanks for the assist, it's much appreciated
Also, the 100% completion reward thing I saw mentioned earlier, is that just the Cernnunos entry in the Book, or is there something else 100% unlocks?
I figured it would trigger a dialogue change in a certain section, if after checking and confirming it's still the same, I'm assuming that's being saved for when all the romance paths are implemented and you can truly 100% all 6
