Search Earl's House for Clues

Once inside, head over to the sofa and find a receipt. This receipt is a surgery receipt for facial reconstruction at the Mega Surgery Center.

Head over there to investigate further.

Talk to Doctor Sun

Doctor Sun is found at the entrance of the Mega Surgery Center in the marketplace area of Diamond City.

Talk to him and ask him about the receipt, and ask him for the cellar key as well. These two requests may require a bit of Charisma to work.

Alternatively, you can pickpocket the cellar key from Doc Sun.

Save and Reload

To easily bypass every Charisma dialogue, especially if your Charisma is not that high yet, you can do the Save and Reload technique where you save before every decision.

If you fail a Charisma check then you go ahead and reload that save, do it until you pass the dialogue option.

Take Grape Mentats

If a quest needs you to pass a Charisma check when your Charisma is on the low side, you may want to consider taking Grape Mentats before talking to someone.

It temporarily boosts your Charisma by 5.

How to Get Grape Mentats

Enter the Mega Surgery Cellar and Deal with Doc Crocker

After getting or receiving the Surgery Cellar Key, head down to the cellar and find Doctor Crocker.

You can either arrest him, end it peacefully, or just kill him. All options lead to his death since he will commit suicide when you choose not to kill him.

Report Back to Ellie Perkins

Doctor Sun will come down after what happened to Doc Crocker. Talk to him and explain everything.

Return to Valentine Detective Agency and report back to Ellie Perkins to finish the quest and receive your rewards.
