Hopefully you were already onboard with For All Mankind‘s sometimes brazenly credulity-stretching alternative reality. The first woman president comes out as gay. Homegrown terrorists blow up NASA HQ. Agency director Margo Madison defects to the Soviet Union and then goes to work in its space agency, only to end up partnering with NASA.
If so, then you won’t mind if a Russian ghost comes back to mess with us now, too.
OK, he’s not a ghost. He’s Sergei, the Russian scientist who seemed to fall in love with Margo and got strangled in front of her to get her to give up U.S. space secrets. And as forces now align to mine the Goldilocks asteroid near Mars, he breaks cover on Earth to seek her out — and maybe not just for more romance.
