@Bortasz Yeah, the author is dragging out the "reveal", I am not sure why.
I dont like how little confidence she has considering how long she worked as the village apothecary. I get the hero and his party constantly talked her down, but it is as if she suddenly thinks she can't heal people despite clearly having had the ability since the start.
And said talking down is what makes the hero dislikable, otherwise I would be sympathetic to him. Imagine how devastated he will be when he finds out his party only associates with him cause of a charm ability he didnt know he had (and its obvious he doesnt know, or healer wouldnt have been let go alive to figure things out and leak the information).
