John Bellasis truly is an idiot if he thinks he can just tell Susan everything, then berate her, and not think that she'd have every incentive to tell her in-laws the truth.
Ugh, even if Oliver is not a bad man, he is still such a whiny ass. By putting him in the country, James may have saved his own reputation as well as Oliver's.
I guess Charles doesn't know how to swim? I don't know how James and Oliver jumping in after him was supposed to help, unless they were champion swimmers themselves. The quality of the Thames water would probably make them all seriously ill.
I don't know if I'd want to see a Series 2, as I find Charles to be a bit bland. However, I'd watch it if it continued to focus on the grandparents.
