I love how much the franchise has expanded with its universe. Its not all about John Wick, the world is filled to the brim with other immensely skilled assassins and characters who'd be badass action protagonists in their own films. Even Chidi and his Myrmidons, who would just be a generic goons in any other movie, are all absolute titans in John Wick 4.
If you go past the credits in the 4th movie, there is a post credit scene where Koji's daughter does kill Caine right as he's walking up to his daughter.
