Wanted to start a Far From Home Spoiler thread because I saw the two post credit scenes and they're pretty big again big spoilers for film.

spoilers:
One scene reveals Nick and Maria are the Skrulls Talos and his wife from Captain Marvel. Real Nick is chillin on a Skrull ship it looks to be in a holodeck type thing resting on a beach and having drinks.

Scene two is in NYC and on a big screen a breaking News Story is playing a recording of Mysterio blaming Spidey for Far From Home events and revealing Peter as Spider-Man. Also J.K. Simmons is playing J. Jonah Jameson and he seems to be the MCU equivalent to Alex Jones.
