Summary
Analysis
Juliet returns Amelia's letter and says she's happy to answer her questions. She says that the Spectator felt that a lighthearted and funny approach to the bad news would boost morale in London, but Juliet no longer feels the need to be so funny. She assures Amelia that she'd never make fun of someone who loves to read. Juliet says that she's asked the Reverend Simon Simpless and Lady Bella Taunton to provide character references. Bella Taunton doesn't like Juliet, so Juliet feels they'll give a well-rounded assessment of her between them. Juliet also encloses a copy of the biography she wrote about Anne Brontë so Amelia can see that Juliet can write seriously.
Compare Juliet's considered and respectful response to Amelia to the way that Mark treats Juliet: while Mark brushes off Juliet's wishes, Juliet takes Amelia's concerns seriously and does everything in her power to reassure her. This shows that Juliet is kind and empathetic, while it makes Mark look like even more of a bully.
