list all the connects between jekyll and hyde

Jekyll pays Hyde's blackmailers.

Edward Hyde is Jekyll's sole beneficiary in his will.

When questioned by Utterson, Jekyll says that he can be rid of Mr. Hyde at any point. As Mr. Utterson gets up to leave, Jekyll tells him that he does have a great interest in "poor Hyde" and apologizes for his rude behavior, but begs him to make sure that he takes care of Hyde when Jekyll is no longer there.
