Confidence Man

Confidence Man is a quest in Fallout 4, where you help the Diamond City Radio host Travis Miles gain confidence.

Quick walkthrough
This quest is given by Vadim Bobrov in the Dugout Inn after the player has encountered Travis at the Diamond City Radio Station in Diamond City. You will have to wait until an NPC like a guard tells you that Vadim was looking for you at the Dugout Inn before you can start the quest, or speak with Hawthorne at the INN and go to the locations he provides and then return to Vadim. The quest is to boost Travis' confidence. This will change how he speaks on the radio.
 * 1) Talk to Vadim. He will tell you that he's going to stage a fight to boost Travis' confidence.
 * 2) Vadim will have the player character come back at 6:00pm to stage the fight.
 * 3) Speak with Travis and convince him to stand up for himself.
 * 4) Defeat Gouger and Bull and talk to Vadim.
 * 5) Vadim will have the Sole Survivor set up Travis and Scarlett, the waitress, to once again boost his confidence.
 * 6) When the player character returns from speaking with Scarlett, Vadim will have been kidnapped by raiders. They're holding him at the Beantown Brewery, north of Diamond City.
 * 7) Speak with Travis and he'll ask to come along.
 * 8) Meet Travis at the Brewery and clear out the raiders inside.
 * 9) Help Travis Rescue Vadim
 * 10) Talk to Travis*

Bugs

 * There is a glitch that causes both Gouger and Bull to be set to essential, making the quest impossible to complete without the use of console commands. Two possible fixes are detailed here and here also this bug can be resolved on the console version of the game or without using console commands by loading a save that is before the player speaks to Travis (the objective "speak to Travis") The player must then go to Beantown Brewery (without talking to Travis) and kill Bull and Gouger who will now be killable. Then the player can continue the quest as normal.
 * The easiest way to deal with this bug is before it becomes a problem. After the fight in the bar, as Bull and Gouger start to leave, enter the following console commands. This will allow them to be killed. ,
 * Note, this bug has been reported fixed in the beta update available on Steam (right-click on the game, select "Properties," and opt in from the "Betas" tab). However, if this glitch is still encountered, simply load a save prior to talking to Travis and exit the Dugout Inn. Once you re-enter Bull and Gouger should be non-essential again.
 * Scarlett may disappear during the fight, making it impossible to talk to her to finish the quest. Some players report that she is outside in Diamond City, near the wall with the podium, and when interacting with her, she is 'on break'. The rest of the quest can follow from there.
 * Following the quest "Confidence Man", Travis might not go back to Diamond city. Diamond City radio will not play and may require teleporting him with console commands
 * Travis may disappear, making it impossible to finish the quest. His marker on the map will show up south of Forest Grove Marsh, on the compass it will show up on the edge of Diamond city, He will be neither place. Vadim will return to the bar although his brother will still act like he is dead. Diamond City radio will still play as normal.
