Dependency

Dependency is a quest in Fallout 4.

Quick walkthrough
1. Talk to Tina De Luca in the reactor room after rescuing Austin and get the quest to help Bobby get off drugs. 2. Talk to Bobby, you can be nice or mean and get the desired result. 3. Talk to Tina again and give her the good news.

Note: It appears that you can talk to Tina OR Rachel about it to complete the quest, though you may not get the option to invite Tina to your settlement if you speak with Rachel.

Bugs

 * Tina's speech check to invite her to Sanctuary may be broken. This can be fixed by telling Rachel that Bobby is coming.
