Some dialogue that gives clues to Trintle being a bad guy.
Brother Estle says 'Brother Chintle is my fellow cleric from the Temple of Life. A few of us were sent to the plains to help out the residents.'
You say, 'who is Trintle?'
Brother Estle says 'Brother Trintle is my fellow disciple. He is best known for his mission to aid the beggars living in the sewers of Qeynos. He spent a month down there. He came back a new man. He is quite an extraordinary young cleric.'
