I mean, we can disagree on tastes and all, but for me Elanor's prologue was mostly unexpected. From her flags and dialogues until chapter 10 i was expecting the typical MC that goes soft and discovers love, mainly because you had Seren and Lily for the most upfront dark choices, so i was preparing myself for a meh more diplomatic and colorful ending, but instead Elanor went full cloack and dagger queen, so every dialogue, mixed with said surprise element, was great. By all means it's not groundbreaking or stuff, but it was a mix between unexpected, awesome and good taste imo.
