After the pilot was made for Constantine, some changes were made that included replacing the character of Liv (Lucy Griffiths) with a character from the comics Zed (Angélica Celaya) who is John Constantine's former lover. Having seen the pilot, am looking forward to the change as I just didn't think Liv fit into the Hellblazer universe… even the one NBC is creating.
Here we have a few picks of Celaya as Zed and a trailer for an episode called Trust where she seems to be introduced.
