My point is IMO all the people who weren't in the original timeline are fair game, male or female

Which still rules out Grace, since she was in the original timeline. She shows up briefly at the start of "Founder's Day" and helps Henry fix the car. He knows of her but doesn't know her well.

I'm with Lyssie on this. If they'd killed off yet another female character of color, especially one married to Henry, I would've stopped watching entirely. It's bad enough that they did it once.
