There's the place where the scales fall from Bertie's eyes when he understands that Jeeves engages in the rough stuff, and the whole Soapy Sid thing... Jeeves making book on Bingo little's love life... and Bertie yelling at Jeeves for taking five minutes to make tea...

But really, from the Aunt Agatha perspective...Bertie has managed to get a fiancee very above himself and is reading improving books and doing quite well and suddenly Jeeves shows up and it's all horse racing and Drones and Bertie messing up every single thing she tries to do to help him get ahead.
