Following Sunday’s episode, some fans now believe that Montague may be alive, due to her having a small, private funeral.
With the UK populace desperate to avoid Bodyguard spoilers, more and more people are watching episodes as they air rather than on catch up.
Fans on Twitter said that it implied Montague had left it for him – and that she was therefore alive.
Bodyguard has been hailed as the biggest new drama on British television in more than a decade, achieving consolidated viewing figures (which includes recordings) of 10.4 million for its first episode.
