What does Winston say is the one thing he and Julia must never do?

In Part
Two, chapter 7,andspend time together in their rented apartment above Mr. Charrington's antique
shop and discuss their future arrest and torture. Winston fully understands that it is only a
matter of time before the Thought Police arrest both of them and tells Julia that later on, they
will be completely separated from one another. Winston then says,

"The one thing that matters is that we shouldnt betray one another, although even
that cant make the slightest difference." (, 209)

Winston proceeds to tell Julia that they will eventually confess to crimes they did or
did not commit, which is not considered betrayal in his eyes. According to Winston, feelings are
the only thing that matter because the Party can make anyone say anything simply by torturing
them. Winston then tells Julia,

"If they could make
me stop loving youthat would be the real betrayal." (210)

Both Winston and Julia are hopeful and trust that the Party has no way of altering a
person's genuine emotions and feelings. Winston firmly believes that his mind and heart are
impregnable and believes that he and Julia will never stop loving each other regardless of the
Party's efforts. Unfortunately, Winston discovers that the Party has mastered the ability to
alter a person's emotions and transforms him into a Big Brother sympathizer after being tortured
in the ominous Room 101.
