"I love these mirrors."
Angel says this offhandedly in Jesús' shop. The statement relates to his vanity as soon after he asks which nose Jesús and Auroroa prefer on him as he shows them different types on card.
"Peel it off!"
De la Guardia gives this solution to Jesús when he tells him his skin has gone dead and strange. But, the peeling off of the natural skin reveals something far worse, even more horrifying to Jesús who does not desire to be immortal as De la Guardia does.
"I am Jesús Gris."
Jesús says this to himself after he smashes the cronos. Moments before he nearly drank his granddaughter's blood as she was bleeding from her hand. He is saying this to strengthen himself in the knowledge of who he is, a man not a monster.
