Erica: Oh really
Demon Sam: Yeah
Erica: Ok well see about that just hang on.

Erica went to go get a book to get rid of the demon

Erica: You want to hear a story
Demon Sam: Sure
Erica: Exorcizamus te, omnis immundus spiritus, omnis satanica potestas, omnis incursio infernalis adversarii, omnis legio, omnis congregatio et secta diabolica. Ergo, omnis legio diabolica, adjuramus te...cessa decipere humanas creaturas, eisque æternæ perditionìs venenum propinare...Vade, satana, inventor et magister omnis fallaciæ, hostis humanæ salutis...Humiliare sub potenti manu Dei; contremisce et effuge, invocato a nobis sancto et terribili nomine...quem inferi tremunt...Ab insidiis diaboli, libera nos, Domine. Ut Ecclesiam tuam secura tibi facias libertate servire, te rogamus, audi nos.
Erica: Bye bitch I'll see you in hell

The demon left Sam's body
