1. Whitney frost and Emma frost are not related
2. Howard is indeed Tony's Father
3. why not? It is a period piece, and after the second World war there was an influx of British to the US.
Cool, thanks
Is there a backstory to Peggy Carter's emigration to the US?
She got recruited to the SSR, which later came to be SHIELD. The SSR was based out of the US, so that is why she is in the USA. The SSR was an integral part of the defeat of the Nazi's, and specifically the Nazi special divisions.
Nice synopsis.
