For those wondering what Sestero says in French, here's the translation.
In the frat: "Hâtez-vous mon ami. C'est là où l'âme de ton frère se repose," = "Hurry my friend. It's there that your brother's soul is resting."
In the house by the lake: "Sort de là et va ramasser les herbes! Petit con!" = "Get out and pick up the grass! Little shit!"
