The film wraps with Kittridge talking with Max and letting her know that she isn’t going to be arrested. They really wanted Jim. Luther and Ethan have a quick chat talking about moving forward. Finally, Ethan is on the plane. The flight attendant asks him the same question that they asked Jim before he got the taped mission at the beginning of the movie: “Excuse me, Mr. Hunt, would you like to watch a movie”. He is going to get his next assignment.
In the Bond series, James Bond usually gets a bit of time off after a mission. It looks like Ethan Hunt gets to jump from one mission to the next.
