I've recently started re-playing Fates again and I've been thinking a lot about the support conversations. I wasn't really excited about the children in this game, but I wanted to have the "best" platonic couples S rank each other purely because the support conversation between the two of them was great (and by "best" and "great" conversations, I mean that the two characters don't suddenly want each others babies for no reason by S rank, but they build up a close and meaningful relationship throughout C, B and A ranks). However, I'm far too lazy to have every character reach A rank to then look over the conversations myself and decide, and I really can't be bothered to watch videos on the support conversations. :/
So, in a short paragraph or in just a couple of sentences, what were your "best" support conversations in Fates? Perhaps don't try to lean towards saying, "xx character and xx character because their child gets xx ability..." because that, unless you then explain why the parents have a good relationship together, defeats the purpose of my question.
(And I do understand that Fates had some bad characters in this game and not all of the conversations were designed to be cute and happy, as some reveal more backstory about another character, so just have fun with this.)
