The first trailer for Spider-Man: Far From Home is filled with blink-and-you-miss-it references and hints about the future of the Marvel Cinematic Universe after Avengers: Endgame. In between explosive glimpses of possible fan-favorite villains, one quick scene offers what's likely our first concrete piece of evidence that Uncle Ben exists in the MCU.

While Tom Holland's Peter Parker is packing for his European vacation, the initials "B.F.P." can be clearly seen on his well-worn suitcase. In all likelihood, this is a hand-me-down that used to belong to Peter's uncle, Ben Parker.

While Peter made a vague reference to his famous uncle, this piece of luggage marks the MCU's first piece of physical evidence that Uncle Ben exists. While the "B" and "P" on that suitcase probably stand for "Ben Parker," it's still not totally clear what the "F" stands for.

In the comics, Uncle Ben never had a middle name, and his full name has always been given as Benjamin Parker in most versions of the Marvel Universe. However, the "F" in those initials could stand for another name from Peter's family tree -- Fitzpatrick.

Before she married Richard Parker, Peter's biological mother was named Mary Fitzpatrick, and the B.F.P. initials could be a sly reference to Spider-Man's mom's maiden name.

While the suitcase is hardly a direct nod to either one of Peter's birth parents, his mom's name could still explain the "F" in Uncle Ben's potential initials. As a quick glimpse at Peter's passport reveals early in the trailer, the MCU's Peter is simply named Peter Parker instead of his usual full name, Peter Benjamin Parker. If the Far From Home filmmakers dropped Peter's middle name, there's no reason they couldn't have turned Uncle Ben into Benjamin Fitzgerald Parker.

The other big surname in the Parker family tree, Aunt May's maiden name, "Reilly," is loaded with meaning for longtime Spider-Man fans. However, the name Fitzgerald hasn't really been used around Spider-Man's world.

For the most part, Richard and Mary Parker don't usually matter. Spider-Man's parents disappeared when Peter was a small child, and Aunt May and Uncle Ben took their nephew in and raised him as their own. For all intents and purposes, May and Ben are the only parents Spider-Man ever really knew.

Even if Uncle Ben's new middle name isn't Fitzgerald, the shadow of Peter's parents still hangs over Far From Home. In the trailer, it seems like Spider-Man will being working with Samuel L. Jackson's spymaster Nick Fury in some capacity. By potentially taking on espionage work, Peter could unwittingly follow in his parents' footsteps.

As Stan Lee and Larry Lieber established in 1968's Amazing Spider-Man Annual #5, Richard and Mary Parker were spies for the C.I.A. In comics, Nick Fury recruited Richard into the espionage business, and the pair met a young Wolverine on one of their missions. However, the Parkers were killed in action by the Red Skull shortly after Peter's birth.

Since that was established, the Parkers have only played an intermittent role in Peter's world. In the 1990s, the Parkers seemingly returned, but those were actually robot duplicates. More recently, their memory re-emerged when Teresa Durand debuted and claimed to be Peter's long-lost sister.

Given their relatively small role in Spider-Man's history, Peter's parents already had an outsized on-screen presence in 2014's Amazing Spider-Man 2. Despite that, Far From Home could provide a natural place to establish their place in the MCU, especially if Nick Fury recruited Peter's father like his comic book counterpart.

While Peter's MCU history still hasn't explained what happened to his parents or Uncle Ben, those questions probably won't stay unsolved for much longer. By the time Avengers: Endgame and Far From Home are released, Tom Holland's Spider-Man will have appeared in almost twice as many movies as any other cinematic wall-crawler, and sooner or later he'll have to come to terms with his family's history.

Directed by Jon Watts, Spider-Man: Far From Home stars Tom Holland, Zendaya, Marisa Tomei, Michael Keaton, Jake Gyllenhaal, Samuel L. Jackson, Cobie Smulders, Jon Favreau, Jacob Batalon, Remy Hii and Tony Revolori. The film is set to open on July 5.
