By Blitz/Blast/Custos logic, aren't Violet and Eclipse related since Claire and Sven are the same. We may have spoke about this.

I've always just decided to leave it up to the interpretation of the characters. Whatever they believe the case may be. Like, Isaac may not necessarily see the Blasts as family, but Violet might think they are, for example.
