Oh god! You're telling me the truth, aren't you...? Oh no! How could they do this to me? For two years? My god, I've been a joke to them! Do you have any idea how easy it'd be for me to sabotage those rockets? That'd be a joke, huh? One hell of a joke!
Chris grew up in Vault 34 and was a vault engineer. However, due to the fact that he liked machines and not guns, unlike all the other inhabitants of Vault 34, he was shunned by them and was sent to work at the reactor. Eventually his hair began falling out due to natural reasons, but Chris insisted this to be a sign of him turning into a ghoul from the reactor's radiation and subsequently left the Vault. Ironically, almost everyone else who stayed in the vault turned into ghouls.
Believing himself to be a ghoul, Chris joined the Bright Brotherhood (who could not convince him that he was human) in 2279 to help them accomplish their goal. Jason Bright was convinced that Chris was sent by 'The Creator' to assist the Brotherhood in their Great Journey. He helps work with the technology in order to get the rockets up and running. However, he had him only supervise the projects and guide the ghouls instead of physically working on the technology, due to the fact that the radiation levels at the area of the rockets would kill him.
The player can convince Chris that he is indeed human with a speech check (50) or with the Black Widow perk, and the rest of the Bright Brotherhood are going on the rockets without him. They are then given the choice to help him sabotage the rockets so the ghouls die in flight. Alternatively, through extensive dialogue you can convince Chris not to sabotage the rockets, he will then accept the ghouls and send them off with no hard feelings before heading for Novac.
Because he thinks he's a ghoul, Chris calls the player smoothskin and speaks rudely to the Courier. He also naturally speaks in the distinct gravelly voice that is typical of ghouls.
After the quest is over, he can be found milling about Novac. If the player talked Chris out of his hard feelings for the ghouls before the launch, but then sabotaged the controls anyway, Chris will remark that he was lucky not to have been on the rockets. If the player admits to sabotaging the controls, Chris will yell, "You bastard! Those ghouls declared me a saint!" and then turn hostile. Though he carries a 10mm pistol, he won't fight back.
"Oh god! You're telling me the truth, aren't you...? Oh no! How could they do this to me? For two years? My god, I've been a joke to them! Do you have any idea how easy it'd be for me to sabotage those rockets? That'd be a joke, huh? One hell of a joke!"
xbox360pcps3 After completing the quest without convincing him of his humanity, he may simply say "Not now, its almost time for the Great Journey." over and over again without acknowledging the fact that they've already left without him. This can happen even if you convince him of his humanity through speech checks. If this happens, he will remain in the control room indefinitely rather than moving to Novac. In order to avoid this bug, make sure to first convince Haversam that he is human (make sure that's the first dialogue you make with him), and then its safe to start his quests (gather thruster and then the green substance). An alternate solution is as followed. After handing over the 2nd item and telling Haversam to start, Jason Bright will start his speech. Player MUST wait (and listen) until Jason will finish his speech. After that Haversam will run to the exit. The bug can happen even if you convince Chris he is human before starting his quests. If Jason's speech still gets cut off and Chris stays stuck in the basement, before telling Chris to initiate the rocket launch, pick the dialogue option to delay the launch instead, leave the area, wait, then speak to Chris again, this seems to fix the bug, Jason will give his full speech, then Chris will run for the exit afterward.

pc While wandering around novac you can kill him without the citizens turning hostile, even if you do it right in front of others.[verified]
pc At bringing of parts quest stage, Haversam can run off up the ladder and never reappear. This happens if player ignored respawning ghouls near compound and entered the basement via hatch.
