Could you give an example what you would consider as "them talking about it in game" that the current scenes with "them" explicitly calling each other family members and such does not cover? Because it seems like you have some scenes in your head and because the game doesn't have them you dismiss everything else as "the words change and that's it"The words the player sees change and that's it. "They" never talk about it in game or otherwise.
I have posted a screenshot just couple posts earlier of Bella saying literally that. At this point i don't think it's the case of game being at fault here, but of massive cognitive dissonance on your part. Let me guess, "it doesn't count because it says it's non canon scene"?I don't recall them ever saying it was in any way taboo to have these feelings.
