Coursework help please?, Gradual Transformation.

Hello guy's,

I am really stuck now because we have not been give an essay guide this time and it's really hard to do this because the question has confused me.

My Essay Question is: At the beginning Dr Jekyll is in control, but by the end Hyde is in control. How does Stevenson show his gradual transformation.

I have been asked to mention.

Settings and Weather
Hyde's Connection with savagery and his isolation
Hyde's Dominance
Jekyll's connection with civilization and society.
Lanyon and Jekyll's confession.
Jekyll & Hyde's as presented by others.
Change in Jekyll apparent to others.
Allegory/Symbolism.

And lots of PEE/PQC to get my target B, i wish i could try for an A but all my C/w have been c/b borderline.

All or any help required, thanks very much. :)

Regards,

Robbie
