Grady's package

Grady's package is an unmarked quest in Fallout 3.

Walkthrough
When you enter the Marigold Station, follow the passage until you get to a big hall. There is a small manager's booth. Inside is Grady's skeleton next to a holotape, Grady's last recording, which explains how to find the package.

Downstairs from the overlook, there are two tunnels next to each other. Follow the one on the right and open the first door on your right. If you have not yet completed the Those! quest, then you should encounter several fire ants on your way. In the first room, there is a door to a maintenance closet, which contains a firehose. Grady's safe key is inside the firehose box. (B on the map to the right)

Continue through the passageway until you once again reach the main tunnels and take a left, then a right. In this next tunnel, turn left and head down the left hand side of the train. You will come to a rotating light and an Easy locked door. You can lockpick the door or use the terminal. Inside the room is the safe (alongside other items such as a Ripper). The safe contains the naughty nightwear. (C on the map to the right)

Once you grab the naughty nightwear, an hapless raider called Lug-Nut will approach you and demand that you hand it to him. He leaves with the nightwear if you give it to him, but it is possible to kill him to get it back. If you choose to give the nightwear to Lug-Nut and then loot it off his corpse after you've killed him, it will have been fully repaired.

The reward for this quest is the naughty nightwear or, if you return it to Ronald Laren in Girdershade, he will reward you with 200 caps (300 if you pass a Speech check). You gain positive karma if the Speech check is successful.

Bugs

 * Before Lug-Nut asks you for the naughty nightwear, drop it on the ground, then give him the suit when he demands it. Kill him as he walks away (no negative karma), then retrieve a fully repaired suit off his corpse, and the original suit off the ground where you dropped it.
 * It is possible that, after selling the naughty nightwear to Ronald Laren in Girdershade, it will not be on his person. This may occur if wearing the naughty nightwear when the exchange is made, or possibly because the naughty nightwear was fully repaired before handing it to him.(confirmed Xbox 360, PS3)
