They held a fan screening of Venom: Let There Be Carnage in the UK over the weekend, and despite Tom Hardy pleading with people not to leak anything...they did.
Venom and Eddie are in hiding after the end of the movie and they're in a room. Venom asks Eddie if he wants to see one second of what his species has been through. Venom does something inside Eddie and Eddie looks strange, but then things suddenly change. The ending to Spider-Man: Far From Home is on the TV, Venom licks the screen saying "he looks tasty" and someone enters the room asking what they're doing in their house/room. The implication is they jumped universes, possibly due to Doctor Strange's spell that brings the original villains into No Way Home.
