You’ll get a chance to do this one after you drop off the supplies with Daniel. Even if you tell him to leave, he’ll stick around until the end. Note that your decision does not impact what happens during your time in Zion.

If you convince him that it’s not worth leaving the Valley for, you can convince him to stay behind. Telling him that it’s dangerous, but that he should see for himself, will convince him to leave. Once you get the chance, you can tell him whatever you liked about civilization. If you wish, you can lie and say that the advice came from Joshua, but there really isn’t much need.

Walk back and talk to Follows Chalk again, and you’ll get your options. He figures that you’re a better source of guidance for him, so he’ll ask you to offer him advice. Joshua will just confide that he isn’t sure. He’ll be waiting by the entrance to the camp, usually in the middle of the river. Note that if you’re doing this quest after talking to Daniel and retrieving the items for him, you will need to travel back to the Sorrows Camp to find Joshua. If you wish, you can offer to talk to Joshua Graham about it. If you talk to him for a bit, he should mention that he’s considering leaving the Valley so that he can go out and see the rest of civilization.

If you talk to him, he should ask you about what you’ve seen of civilization. You should be able to just travel back and find him back somewhere near the camp fire. Follows-Chalk will then walk back to the Dead Horses camp. You’ll probably need to talk to Follows-Chalk again after you finish up the first round of quests for Joshua Graham and meet up with Daniel in the Sorrows Camp. This one is a fairly simple quest, but it’s slightly hidden. Follows-Chalk - The Civilized Man’s Burden
