The NUN -post credit scene - Horror The Conjuring

The Nun‘s ending, a quick recap: Sister Irene (Taissa Farmiga), Father Burke (Demián Bichir), and a friendly local French-Canadian named Frenchy (Jonas Bloquet) have seemingly banished Valak to the fires from whence he came using a vial of Jesus Christ’s blood. (I assume every convent has one.) With the Cârța Monastery restored to sanctity, our holy heroes ride off into the Romanian sunset, with Frenchy—real name Maurice—voicing his desire to become a farmer. A quick shot reveals an upside-down cross—basically Valak’s house sigil—embedded in Maurice’s neck. Flash-forward 20 years to…a scene from The Conjuring. Ed (Patrick Wilson) and Lorraine Warren deliver a lecture on possession at Massachusetts Western University while Carolyn Perron (Lili Taylor) looks on from the audience.
The subject: Maurice, “a French Canadian farmer” with “nothing more than a third-grade education” who suddenly “spoke some of the best Latin” Ed Warren ever heard. We see Maurice, in grainy footage, grab a screaming Lorraine as The Nun cuts to credits.
