Perhaps Loeb was embracing brevity due to the constant Reddit AMA questions popping up, but I would prefer to hope that his answer is indicative of a legitimate Inhumans crossover episode (or arc) coming to Agents of S.H.I.E.L.D. in an upcoming season.
To play devil’s advocate here, Jeph Loeb is no stranger to dishing out generically positive responses to questions about the chances of various Marvel TV shows coming together for crossovers.
That said, most of those generically positive answers are supplemented by formulaic explanations about why it’s difficult to, for example, make Defenders heroes take the streets alongside the teen heroes of Hulu’s Runaways.
