I read this a bit ago but Ethan never tells Vincent that she’s Paula. When the Paula wanted to make the kid happy she suggested using colored inks to write the letters and one of the letters were directed to Vincent. And if you remember early that there used to be colored inks used in Ethan’s household but this ink can only be bought oversees. This is where Vincent starts to catch on but he isn’t quite sure yet. Later on Violet decides to visit her son and she recognizes Paula, the sister pretends like she’s Paula but Violet knows what Paula looked like and just like that the truth was out
Vincent slowly figures it out on his own and eventually confronts Paula. We still have a way to go though.
Not to completely spoil it but it’s a scene in the woods, so you can lookout for that
Who read the novel. Pls spoil me huhu when will vincent discover/realize she’s Paula. Will Ethan tell? WAaaaaaa
