One of the big mantras of the Marvel Cinematic Universe is "everything is connected," with their superhero movies often planting seeds that will sprout in future adventures. After eight years, fans have grown accustomed to scouring for connections and Easter Eggs throughout the movies, and many fans pointed to one particular aspect of Captain America: Civil War, which may offer a connection to the upcoming Spider-Man: Homecoming. If you haven't seen Captain America: Civil War yet, there will be plenty of spoilers below, so be sure to read on at your own risk.

Captain America: Civil War opens with a flashback, where Hydra agents are programming Bucky Barnes (Sebastian Stan). Part of this programming involves a number of random trigger words, which, when said in sequence, turns Bucky Barnes into the heartless Winter Soldier, a ruthless killing machine. One of these seemingly random words is "homecoming," which many fans found interesting since, just a few weeks ago, the title of Sony and Marvel's Spider-Man reboot was revealed to be Spider-Man: Homecoming. CinemaBlend managed to catch up with writers Stephen McFeely and Christopher Markuks, who claim the connection is purely coincidental. Here's what Stephen McFeely had to say below.

"When you're making so many movies, everybody is looking for connections, it's absolutely natural to think, 'Oh my god, they've got their fingers on everything, and everything means something!' And often it means something, but not always."

There had long been rumors that Sony and Marvel were negotiating a deal that would bring Spider-Man into the Marvel Cinematic Universe, which was finally announced back in February 2015. Tom Holland was cast in June of last year, just after production started on Captain America: Civil War. Stephen McFeely's writing partner Christopher Markus admitted that sometimes inadvertent connections can happen, which will be explored later, but that's not the case with this presumed "Homecoming" Easter Egg.

"That's also part of the fun. Sometimes unintentionally you can create a connection and then play with it later - even if you didn't mean it that way in the first place! This one... it's simply not."

The full list of trigger words include "longing," "seventeen," "daybreak," "furnace," "nine," "benign," "homecoming," "one" and "freight car." When asked if there was any symbolic meaning behind any of the other words, Stephen McFeely said these words were chosen because of the way they sound. Here's what he had to say below.

"They're rhythmic and enigmatic. I can't remember if we listened to them in Russian to hear if they sounded suitably intimidating, we must have. Because they were really melodic; I'm not sure we would have gone with them [if they weren't]. But we wanted ones when you read them on the screen you'd have some reaction to it. Like 'Duress,' and 'Freight Car.' It's really just us coming up with stuff. There's not a lot of rhyme or reason to it."

Of course, now that fans are picking up on this connection, it's possible that Marvel may actually explore ways to connect this random key word used to activate The Winter Soldier, with the story of Spider-Man: Homecoming. Of course, there's nothing we know about the story at this point, except that Tom Holland's Peter Parker will be in high school, juggling his school work with his covert crime-fighting activities. We'll be sure to keep you posted with more from Captain America: Civil War and Spider-Man: Homecoming as soon as more details surface.
