I personally think Jemima is the youngest Jellicle, and obviously the
sweetest. Even though she is young, she seems to be mature enough to
hang around Bomby or Demeter sometimes. It's hard to believe that
someone like Tugger would be so interested in Jemima. He seems to like
her a lot, and flirts with her occasionally. Just as some others have
said, it looks like she will be paired up with a different mate:
Tumblebrutus. If you watch the bottom of the screen on the movie during
Victoria's "Mating Dance", you see they are playing around with each
other in a lazy sort of way.

I agree that Jemima is somewhat VERY connected to the moon. That
is why she is so connected to Grizabella, who portrays the same
features. 

Now what about her parents... I do agree that she is Dememter and
Macavity's daughter. Somehow, deep inside her, I think she knows that
Macavity is her father. If you watch every time that Macavity is
mentioned, she seems frightened, MUCH like Demeter. But what I question
is... how can a such a bad cat like Macavity be the father of such an
adorable, innocent, playful, and loving kitten like Jemima?
Shimbleshanks, I have noticed, has been kind of like a "Substitute
Father" for Jemima, so maybe she will feel secure with such a gentle
cat, MUCH unlike Macavity. If you have any questions or complaints,
email me at kutie197@hotmail.com.
Thanks!
