A thought probably wrong, but why not:
Maria got a 'completely different name' from the one Kinzo wanted her to have, but still in the same design pattern. Rosa doesn't sound like she's the one to defy Kinzo openly, or at least, the first to go out and do it. One would think that if she dared to name her daughter Maria instead of whatever Kinzo wanted, prior experiments had to have occurred.
Could Jessica or
Maria be the onboard "Erika"?
If not, which red in particular stops them and when?
