Episode 4

What was intended as a day of fun turns into a day of agony for everyone on the Box Hill excursion.

Things come to a head when, egged on by Frank, Emma behaves badly, insulting Miss Bates. She is berated by Knightley and realises that her behaviour was shameful. She tries to repair things with Jane and Miss Bates, but Jane will not see her - although Miss Bates tells her that Jane has accepted a job as a governess - and cried all night.

Meanwhile, Knightley goes to stay with his brother in London and will be away for a while. When Frank's controlling aunt dies, the Westons expect him to propose to Emma - but his actions set in motion a chain of events that both shock Emma and make her realise something that has been in plain sight all along.
