They are hostile no matter what you do to Petrus because they all went hallow...just like the knight at the very beginning of the game. you talk to him then he tells you he's gonna die and go hallow and says he's sorry if he will attack you afterwards. Same thing happened to Reah's party...they lost their mind. Just as it will happen to Solaire later on if he finds he's "sun"

Well Solaire is an exception in that he doesn't go hollow, he's just batsh*t insane at that point lol.

A damn shame isn't it? That's what you get for saving them from a traitor.

Are you an idiot

It was a fat joke y'all

This happened to me too, I hade try to leave firelink and return or quit the game ane reenter but He keep telling me that is gonna leave. Even petrus just keep repeating the same line he tell when he return from the tombs of giant and no mention on the saving of Reah

I’m assuming you’ve already collected the fire keeper soul from the sunlight alter. The problem you are experiencing is that you’ve entered Blighttown where the second fire keeper soul is located. That is the trigger to get the “I’m thinking of leaving” dialogue from Lautrec.sadly, you won’t be able to get that dialogue anymore but it shouldn’t affect the rest of the quest line.
