WARNING: The following article contains spoilers for Spider-Man: Far From Home, in theaters now.

One of the biggest surprises of Sony's Spider-Man: Far From Home came at the very end of the film, when the post-credits scene revealed that Nick Fury was, in fact, Talos, the shape-shifting alien Skrull last seen in Captain Marvel.

The twist obviously came as a shock, with fans trying to figure out when the switch was made. However, it turns out it isn't all that complicated. In an interview with ComicBook.com, Far From Home director Jon Watts explained the details of the switch.

"First of all, to clarify the timeline, that's real Nick Fury at Tony's funeral at the end of [Avengers: Endgame]," Watts said. "So it's not like he's been a Skrull forever or like, it's not like he's been a Skrull since Captain Marvel."

Watts then went on to reveal that, at a certain point, the production team considered dropping more hints that this wasn't the real Nick Fury by showing the super spy cutting his toast diagonally, something he said he never did in Captain Marvel. "We were going to have him eat diagonal toast cut diagonally." However, that one might have been too obvious for some fans. "You know that one? That would've given it away."
