AOne of One Foot In The Grave's most appealing attributes as a programme was its ability, albeit through the genre of comedy, to be true to human nature and show a much darker, edgier side in its portrayal of suburban life. This was never done better than in the last moments of the final episode, where Margaret, who having found out her close friend Glynis was responsible for killing Victor, is afforded the chance of swift revenge by drugging her drink. However, we don't see on screen whether or not Margaret has taken this opportunity. Writer David Renwick has since said this was deliberately left ambiguous and not even he knows whether Margaret did it, preferring to allow fans to make their own minds up and finish the series in whichever way they feel is appropriate.Despite such a vengeful act seeming out of character for Margaret, she swears throughout the show that she will seek justice for Victor by doing to his killer what they did to him. This seems to suggest that Margaret would indeed kill Glynis, but other factors should be considered. Margaret is told by a priest in the episode that he hopes and prays she will find the forgiveness to avoid taking revenge on Victor's killer, and in addition to this, Margaret was not expecting one of her friends to be revealed as the guilty party either. Hearing the exact details of the event and how it came about may have changed Margaret's mind. However, we don't know and aren't meant to know. It is left in the balance and in truth, neither answer is correct.
