In episode 2 of Bodyguard (the 2018 BBC drama), Home Secretary Julia Montague meets a man for dinner. It transpires that none of her other friends have been told to attend, even though she was expecting a group dinner. It appears that the man has engineered the dinner to be just for the two of them. Julia says that the situation feels 'weird', and leaves with her bodyguard DS Budd. The man left behind looks crestfallen.
