By the end of the finale, Principal Wardwell — who I suppose we're just calling Lilith now — gets on the winning team and helps Sabrina fight the Dark Lord for both of their freedom. After they successfully bind Satan in the body of Nicholas Scratch, it's finally Lilith's time to shine — though it was a pretty casual celebration.
I love how low-key this coronation was! After everything she goes through (and puts Sabrina through!), Lilith just plops the giant gold crown on her own head, throws out a couple of miracles to thank Sabrina for her service, and carries Satan-Nick into the pit of hell. But before she goes, Lilith reminds Sabrina of her power and freedom: "May you never give up either again."
