They made a distinction with Alexandra and Henry. Henry would have been left all alone because the curse would have wiped out everybody not of this world and even though Alexandra was born in SB, she was conceived in FTL and Adam clarified that on twitter and said that was why Henry would have been alone.
So, hypothetically if Tamara is RH’s daughter, she would have been wiped out too and isn’t 100% from our world. I don’t think they lied in either instance though so it makes me hopeful maybe she isn’t RH’s daughter after all. (Which would be my preference). I’m not sure how they could have said she’s just human if she were in any way connected to FTL through birth, especially after clarifying the thing with Alexandra (thanks for reminding me of that!). Adam could have said they just didn’t mention her and that Henry would have been alone in Regina’s eyes because all of his family would have been gone etc etc and that really Henry would have had to take care of Alexandra all by himself, but Adam said Alexandra was conceived in FTL so it made her different per the failsafe trigger so I would think the same would be true of Tamara and her humanness. It’ll be interesting to see how they approach that though. I really don’t think they lied so I’d like to think that they’re consistent about it and they’ve said repeatedly she’s human.
That being said I think for sure something happened to her (similar to what happened to Owen) and that magic has affected her life in some super tragic way, but this does raise the issue of how is she just a person who is part of this organization if she’s related to (and in existence in some form or another) in FTL prior to coming to our world?
