Last week, this series returned with a two-episode premiere that cast the S.H.I.E.L.D. agents in space, on a ship run by malevolent blue aliens. Simmons was “adopted” by them, as a sort of slave, and tonight, Daisy takes some great risks to lead a rescue mission to rescue Simmons. But after that, what? And where? And, if time travel is a factor, when?
