Sorry for the late reply, I don’t use the forum much.
She frequently belittles or interrupts Red in ways I found to be super disrespectful, and then often “apologizes”, only to keep doing it. It’s a type of emotional abuse I’ve seen IRL quite often, and I found it deeply unpleasant in this game.
She never really grows as a character, you’re just supposed to like her because the game says so. When the game hinges so much on this relationship, and one half of that relationship is just such a nasty person… Kinda raises an eyebrow for me. But I loved so much else about the game I still strongly recommend it.
