"Right, we're just down here-"

James points the way. 

Down he goes. He knows his stuff. And the 'bots are talking to his helmet, if anything suspicious happens outside.

Two days later, the purifier has power, and the controls work. James looks very pleased with the work that's been done, and has even begun trusting Nick to repair parts on his own. 

"I wouldn't trust me if I were you, you know. I'm still a selfish wasteland captain."

“Why do you think I’ve got Amy watching you?”

She salutes from her spot nearby. 

“Play nicely,” Madison says as she passes. 

"Whatever, then. I'm itching to move on - or get paid again - and will probably skip out tonight. By the way."

Before James can speak, Madison butts in. “Would you mind if we hired you again to collect the GECK? James narrowed down the right Vault.”

"Well, caps talk. For the right price, my robot horde is at your command."

"I'm afraid we wouldn't be able to pay you, as we did for the previous job. We can offer you this, however." 

Madison nudges James, who reluctantly offers out blueprints. "These are for self-cooling energy turrets. I thought your ship could use something a little more precise than rockets," Madison says with a soft smile.

"I do have some slug-throwers. This has... Potential. Especially if I can figure out how to wire them right into the main power system and not use energy cells. Permanent sustainable upgrades are always best. Hmm... I think, deal."

"Wonderful. We'll give you the co-ordinates. You should be able to get back here within a couple of days."

"Am I going with him?"

"I- We'd rather you stay. In case something happens."

"Okay then." Amy's smile is very smug.

"Oh, so nothing's stopping me from taking the GECK and running off to Canada?"

"Nope! We unfortunately just have to rely on your goodwill and compassion." The twinkle in Madison's eye says she doesn't believe in either, but is willing to take a chance. "Luckily, the GECK doesn't particularly function as a good weapon for a trader."

"You'll be back. We've got too much fun tech lying around."

"And I have professional standards and a reputation to maintain - you've acted honorably so I will do likewise unless it becomes unusually hazardous around here. Anything else before I head off, then?"

"Good luck."

"Give the boys my love."

Well then...

He heads off to the listed vault, and prepares the bots for Vault-diving. One of them gets scanners, lockpicking, and terminal-hacking tools instead of its usual loadout.

One week later, and Vault 87 has been plundered of its treasure, the GECK.
