WMG / Johnny English Strikes Again

The whole movie is an Interquel set before Reborn

It'd be a more plausible way to explain Bough's no-show. Also Johnny's lost his fancy martial arts from that movie, where he's also a much more broken individual due to Mozambique. Also the outsourcing of MI7 is somehow undone. Tucker is just young enough to have been his student, inspiring him to join MI7.
