When Follows-Chalk was a young boy, a man came through the valley with one of the caravans "Tall man, big moustache, carried a guitar". Follows-Chalk asked him what he did for a living, and the interpreter told him that he was a singer. "What is that?" he asked. The man explained that he went from place to place and sang for people, who gave him food and shelter and care in return. Follows-Chalk couldn't believe that there was a place in this world where a man could do that. He promised himself then that one day he'd explore that world himself.
Follows Chalk's name is derived from the fact that the more experienced Dead Horse scouts leave chalk marks to indicate areas where game is plentiful. As he is not a full scout yet, he simply "follows the chalk" of the veterans. As a young tribesman, he admits to not believing in the local taboo legends, and expresses excitement when exploring taboo areas (pre-War buildings). Follows-Chalk idolizes Joshua Graham, which worries Graham, who feels he should have as little influence over the tribe as possible.
Bighorners of the Eastern Virgin: Follows-Chalk informs the player that the bighorner are becoming restless over the loss of one of their calves. He asks you to return the missing calf, or else the bighorner will stampede into the Dead Horses camp.
Civilized Man's Burden: Follows-Chalk is fascinated with civilization outside of Zion. The player can convince him to either explore it for himself, or tell him to stay with his tribe.
Arrival at Zion: After crossing the bridge and escaping the White Legs assault on the caravan, Follows-Chalk finds you and leads you to the Dead Horses camp.
As with other companions, Follows-Chalk will make several comments to the player. Some of these comments are unique to certain locations. His repeating comments include references to various local happenings (both current and legend) and many comments about the "civilized" lands outside Zion. These include asking why people would pay to watch cards be put on a table, referring to Vegas and blackjack.
Sometimes, when Follows-Chalk is knocked unconscious, he will say "Oh, look... I'm not dead" upon regaining conciousness.
Follows-Chalk took the Courier's words to heart and decided that the big cities of the Mojave Wasteland and NCR were best left unexplored. Though he sometimes dreamed of distant lands, he continued to support his family at Dead Horse Point, and eventually his wanderlust faded.
Follows-Chalk took the Courier's words to heart and decided that he would behold the sights and sounds of distant lands with his own eyes and ears. After returning to Dead Horse Point, he quarreled with his family and other tribe members about his ambitions. One morning, they awoke to discover that Follows-Chalk had set off alone, westward, into the wilderness. He was never seen again.
Of the Dead Horses, Follows-Chalk has the most grammatically correct speech and enunciates the clearest.
His warclub already has the bullet casing ridge, despite him not being a full scout yet.
In his first appearance, Follows-Chalk can easily be mistaken for a White Legs tribal. Should the player kill him, multiple quests will be failed, and the Dead Horse faction will turn hostile to the player, including Joshua Graham.
If storing items on Follows-Chalk, once Waking Cloud is recruited you will lose Follows-Chalk as a companion permanently and all the items will turned over to the Courier.
Follows-Chalk will have different dialogue should the Courier manage to evade (most of) the White-Leg ambush at the beginning of Honest Hearts. He will try to persuade the Courier in assisting him to eliminate the remaining White-Legs in the area.
