Major Story Arcs

Newcastle

Anne-Marie was one of the amateur magicians in John's "Newcastle Crew" who were present during the botched exorcism of Astra Logue. The demon Nergal badly scarred Anne-Marie during the ordeal (he initially appeared to her in the form of Constantine). His lasts words to her were from the play Hamlet "get thee to a nunnery".

Swamp Thing

Decades later, Anne-Marie (now a nun based in Washington) was the first victim of the Brujeria's plan to destroy the friends of John Constantine. She was attacked and killed by the creation the Invunche while she was traveling on the London Underground.

Other Media

Constantine

Australian actress Claire van der Boom plays Sister Anne-Marie in episodes 8 & 9 of the NBC series Constantine. Much younger than her comic counterpart, the two were once romantically involved, though Anne-Marie felt betrayed when John didn't return her affections and pursued other women. She also was one of the people to introduce John to the world of the occult.

Still angry with John after the Newcastle affair, she contacts him as a last resort when the demon Lamashtu began stealing babies from her convent in Mexico.
