Drizella has to kill Gretel to join the Coven. This mirrors Ana’s test as the Guardian. Drizellla kills Gretel (which is why we didn’t have the HH counterpart). Ana turns Drizella into a young girl again to have a do-over.

Nick is not working with Gothel but going after known witches in the Coven (which will explain why Nick didn’t go after Regina yet). Thus, Drizella didn’t randomly get picked up by Gothel but was apart of the Coven for a few months and got her prophecy from one of the Witches. Well, Nick wouldn't go after Regina or Zelena. He knows Zelena is a good guy and he saw Regina cast the curse to save her son - who he is also friends with. As he remembers (as it's been confirmed the killer is someone who remembers), he'd know the truth behind it all.
