Thank you for your reply, Ataashi. 🙂
Sadly it's not the poetry scene i remember either, even though it might very well seem so.
The scene i recall is that (please forgive me if i've already discribed the scene. i have a very poor memory.); She is reading the book like normal, and it's the normal scene and all. Then when you talk to varric about the next book in the series, is where it changes. i don't recall how, but i just remember that he didn't come with. The inquisitor then hung the book in front of her face like bait. She starteled and stood up. the inquisitor teased her with the book like he would in the scene with varric. Cassandra made an attempt to snatch the book, but the inquisitor took a step back out of her reach. Saying something like, "well, if you don't want the book it still shouldn't go to waste." as he wondered of pretending to read. Finally Cassandra gives in and says yes to wanting the book.
After that the memory gets blurry and i might as well be making it up. It might still seem like it with the scene being so elusive. (Btw, sorry for taking up your time on such a wild goose chase. 🤭)
I thought as much would be the case, though i hoped i had missed a somewhat hidden scene or item or something, to give a sort of hidden option when talking to Varric.
Again, i don't know for certain that it was even a part of the game.
Thanks again for your time and reply. I really really hope i'm not making all this up and just wasting time... 🤭
