The actress is Ethiopian/Irish . The fact that at one point she lived in Asia doesn't mean she is Asian - the very white Cal Zebo was there at the same tiome

He was in The Magical Place as one of the Centipede soldiers

She was also Dottie's double in Agent Carter.

Natalie came out to Bay way,way back in 2x06 and there was no big deal reveal/stunt episode to do it either just Natalie signing I'm into this girl and Bay making no deal about it at all .
