Octavius kept going. He couldn't let the screams distract him. He didn't want to cause pain but this was necessary. The demon had to be cast out and not just simply thrown to another body but thrown back down to where he came from.
"Exorcizamus te, omnis immundus spiritus, omnis satanica potestas, omnis incursio infernalis adversarii, omnis legio, omnis congregatio et secta diabolica," he cried out. "Ergo, draco maledicte et omnis legio diabolica, adjuramus te ... cessa decipere humanas creaturas, eisque æternæ perditionìs venenum propinare. Ut Ecclesiam tuam secura tibi facias libertate servire, te rogamus, audi nos."
If it worked, these last words should throw the demon out.
