Seeing as how Honest Hearts' endings consist of either helping the Sorrows to flee Zion or to hold their ground and stay, two variations of 'good' differing in interpretation according to Daniel/Joshua, I wonder whether there could have been a third, just plain 'bad' solution? For those on Legion playthroughs, surely wiping out the Sorrows on behalf of the White Legs would have been a fine way to gain some Legion fame? Kill Salt-Upon-Wounds yourself, and rally the White Legs to follow your brutal leadership? Command your own tribe! Onto Graham. In one of my saves I hadn't yet met Caesar and so it was the perfect opportunity to complete HH and then pay him a visit. Upon doing so and getting him to open up after doing the first couple of quests...no new dialogue options on the Burned Man. So then I replayed that save the other way around, meeting Caesar first and then doing HH, and it was quite clever for the developers to account for that... You get a dialogue option to tell Graham that you've already met Caesar, and what would happen if you told him JG was still alive, to which he responds something along the lines of "That would put you, and Caesar, in a difficult position. Even if you did try to convince him, Caesar wouldn't publicly acknowledge it, for doing so would be admitting that he was wrong. That Caesar made a mistake". Makes sense, really. (Apart from the fact that in the previous variation I was wearing Graham's armour - that same armour he had worn at the first battle of Hoover Dam - and had his unique, signature Burned Man .45 with me at the Fort. With all that street cred, STILL no one seemed to bat an eyelid). So don't be disappointed if there aren't any additional dialogue options with Caesar, just think of it as your own special little secret with the Burned Man.
