I also think the earlier argument about Vernal was that as a one-note,  flat character, she's fine. There isn't much to her, nor was there going to be, and we quickly establish her relationships to the rest of the cast.

Some characters in shows are not meant to be especially important to the narrative, and only seem important due to a relationship with another character. Sometimes we get a Daario Naharis. And there ain't nothing wrong with that.
