Detailed walkthrough
Upon entering the Reactor room of Vault 81, after completing Hole in the Wall, you'll find Tina De Luca working. Talking to her she thanks you for helping Austin, and proceeed to ask you to now help her brother Bobby De Luca kick his jet addiction. She informs you that since the incident involving Austin his addiction has gotten worse, and Rachel has warned that if he doesn't get clean soon he could die. Rachel has a treatment for Bobby and Tina asks you to convince him to go see Rachel.

You'll find Bobby in his room shooting Jet. He questions why you're interrupting him and you can choose to be either compassionate and convince him to go see Rachel, or aggressive which can cause Bobby to go hostile and attack you. Upon convincing him he will walk to the clinic where you can inform Rachel of his choice. She'll complement you on being a good friend helping Bobby overcome addiction. Once Bobby arrives she explains the process and administers Addictol.

Bugs

 * Tina's speech check to invite her to Sanctuary may be broken. This can be fixed by telling Rachel that Bobby is coming.
 * Even if you successfully invite Tina to your settlement and then finish the quest by talking to Rachel she will remain in the Vault 81. If you talk to her again she will mention "seeing the Commonwealth" and "finally getting out" but she won't join the player anyway.
 * Successfully completing Tina's speech check to invite her to a settlement can lead to the quest becoming impossible to complete, with the objective to speak with her not not marking as complete and it being impossible to initiate conversion with Tina again. Going to talk to Rachel (who has no marker) seems to allow this to be bypassed and the quest to be completed.
 * After talking to Tina, you can go to Rachel as well as Bobby. Going to Rachel first and asking about the Addictol can lead to her asking you to bring Bobby to her. However, going to Bobby reveals him in his room, inhaling Jet and refusing to respond to you at all.
