Another film set within the world of Tenet showing exactly the missions The Protagonist and Neil undertake would be the perfect excuse for a follow-up.
In fact, The Protagonist is the one who signed Neil up to this particular mission – only he hasn’t done it yet.
However, he couldn’t resist peppering in a few hints that are sure to stir hope among the film’s bigger fans.
Neil, having helped The Protagonist carry out his mission, goes on his way, describing this moment as the end of what he describes as “a beautiful friendship”.
