Is Weena necessary to the story of the Time Machine?

Weena is the only representative of the Eloi that the Time
Traveler becomes very familiar with.  She represents all that is good and bad about this
future race of people that is bred like cattle by the Morlocks.  It is through observing
her behavior that the Time Traveler learns about the relationship between the Morlocks
and the Eloi.

In the story, Wells only gives names to
characters that are important, and Weena is one of them.  We are given an emotional
attachment to Weena and begin to care about the Eloi through her. Without her we might
not care enough about the Eloi or what the Time Traveler tries to do, and the story
would not have the emotional impact that it has.
