Between these two, I now felt I had to choose. My two natures had memory in common, but all other faculties were most unequally shared between them. Jekyll (who was composite) now with the most sensitive apprehensions, now with a greedy gusto, projected and shared in the pleasures and adventures of Hyde; but Hyde was indifferent to Jekyll, or but remembered him as the mountain bandit remembers the cavern in which he conceals himself from pursuit.

To summarize this excerpt correctly, what is the main event the reader should include?

Jekyll did actually remember some of Hyde’s feelings and actions.
Hyde did not really care about Jekyll and kept him in the background.
Hyde and Jekyll were both parts of Jekyll and shared some memories.
Jekyll had a hard time choosing between being Jekyll and Hyde.
