An easy-to-miss detail in WandaVision’s Westview incident. It seems that even though Fury isn’t the director of SHIELD anymore, he’s still very much in-the-know when it comes to important events going on in the MCU.
It was the Captain Marvel’s Talos (Ben Mendelsohn) was using his Skrull shapeshifting abilities to pose as him on Earth, while the real Fury was on board a spaceship and in with his impersonator. As time ed, it became increasing apparent that Far From Home was hinting at SWORD, a peacekeeping organization in the Marvel comics similar to SHIELD, that fights alien threats. Viewers finally got to meet SWORD in WandaVision episode 4, where it was confirmed that they were monitoring what was happening in Westview.
A shot in the Spider-Man: Far From Home post-credits scene indicates that SWORD itself wasn’t its only WandaVision connection. Fans have pointed out that on Fury’s ship, there’s a screen that features a hexagon shape. This is important, because it was specifically stated in WandaVision episode 4 that the energy bubble surrounding Westview is shaped like a hexagon. We've seen this hexagon shape in the MCU before; it was introduced in Guardians of the Galaxy Vol. 2 as the shape of a jump point in the Universal Neural Teleportation Network series of wormholes in space. It being used again in WandaVision is purposeful. What this potential Scarlet Witch Easter egg could imply is that at this point in time, Fury already knew about the Westview situation. He presumably wouldn’t have known exactly what was going on per se, but he did at least have access to the same information that SWORD had obtained as of episode 4.
Though it's certainly interesting that Marvel included this, it’s wouldn't be surprising if a character like Fury were to have this knowledge. Plus, the timing of events lines up. The recent episode has shown that the series takes place shortly after Nick Fury's relationship with SWORD, which Marvel hasn’t been clear about thus far. Some believed prior to WandaVision episode 4 that Fury could be the one in charge, but now it’s known that Tyler Hayward (Josh Samberg) is the acting director.
Regardless, it appears that Fury is working closely with SWORD, and is continuously being updated on their activities on Earth while he’s off-world. This is naturally consistent with who Fury is as a character in both Marvel Comics and the MCU. Whether he’s the director of SHIELD or not, Fury is an incredibly well-informed and well-connected person who keeps tabs on all sorts of unique situations. It could be that as the problem with Secret Invasion.
