Still we have eye that can have(just guess) major influence on 3rd evolution.
Maybe with horn possible to kill Valvaran without Brianna, but eventually this would be bad decision.
Honestly I like the novelty of making my choices as if I was MC. It's kind of an RPG game to me tbh. I chose the eye and won with Brianna's help. Idgaf about how much Nico likes or dislikes me. I won without going back, as if I was the Superhuman MC, which is much more engaging and fun imo.
But then again, everyone can choose how they want to play this game. Just sharing my perspective.
