Hmmm theory time kids. So in the Netflix Daredevil series. Nobu and his associates wanted a series of buildings throughout Hell's Kitchen for an unspecified reason and he got really upset when Fisk tried offering him different ones. Now we know that this group is more than likely the Hand the group Stick and the Chantry are fighting like in the comics.
When Stick is asked if Murdock will be ready when the door opens he state he has no idea.
So here is my theory. That threat they were talking about...I am betting whatever is going to happen will be the big evil the Defenders will need to battle and I am betting the buildings Nobu acquired will be involved with some part of the plan.
A couple of threads on the imdb.com message boards asked a question about Black Sky and my theory was that whatever Black Sky's purpose was, it had something to do with those buildings (or their location). So my guess was that, for full effectiveness, the location and the use of Black Sky would have been necessary, something ritualistic perhaps. Since the Black Sky plan fell through, I would say there's no reason for those same buildings to hold the same level of significance, or at least not for the same reason any longer. But the Hand is by no means finished, and now that Fisk has vacated the seat of power and Gao is nowhere to be found, they'll have free reign to come in and take over the old operations. Surely Elektra's presence is significant for their continued menace in the series, and even two hard-hitters like Daredevil and Elektra can't stop them all, so the wild card, Punisher, who may or may not understand the full situation, is a powerful ally, and I suspect his role will mainly be to force Matt to confront his own stance on killing to stop an evil person or group. Whether by accident or design, I think Matt will end up killing a bad guy and have to deal with that guilt throughout the season.
Aaaaaaand withou further ado, the final Batman Vs. Superman trailer before the film's release...
Just really blown away by the fact that they're not skirting around the fact that Bruce is getting old, they're declaring it, like it's not a huge problem. Really delusional creative decisions just keep mounting. Scary.
