After Charles bails out of marrying Henrietta and is feeling terrible about it, and the others aren't exactly impressed with him, Tom pipes up that if he really wasn't sure about marrying her, then he was right not to go through with it. Fiona, who throughout the film has been responding to all Tom's remarks with an irritated "Bugger off, Tom", looks as though she's about to say it again — then she just touches him on the shoulder and says gently, "Quite right, Tom."
Narm: Andie McDowall doesn't exactly give the most electrifying performance of her career here. Especially "Is it still raining? I hadn't noticed."
