There are obviously no guarantees that anything will ever come of this reveal, in the sense of Detective O’Reilly showing up in a Luke Cage flashback or anything like that, but the extremely close timing of the dual references seemingly implies how intentional it all was.
So there’s hope that Marvel TV head Jeph Loeb has figured out a way to make multi-network crossovers happen without gumming up the works.
Though it seemed like the MCU would be rife with crossovers back in its early days, production logistics have largely rendered film-to-TV crossovers non-existent, and the same mostly goes for TV mash-ups outside of Netflix’s Defenders-based team-ups.
