Grady's Package

 is an unmarked quest in Fallout 3 which can be done alongside the Those! quest.

Beginning the quest
The quest may begin on the corpse of Grady, located on the first mezzanine inside Marigold Station, though you can complete the quest without finding Grady's corpse, so long as you find Grady's safe key inside the fire hose case in the maintenance room or pick the lock on the safe.

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 here there should be two tunnels next to each other. Follow the right one 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 NPC called Lug-Nut will approach you and demand that you give 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. Alternately, you can Mezz him before he takes it and get 250 caps when you return to Paradise Falls.

Rewards


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, or 300 if you pass a speech check. You do gain positive karma if the speech check is successful.
 * You can attempt the speech check for the 300 caps, and if it fails you can still receive the good karma along with the 200 caps that comes from clicking the "Sure, here you go" option afterwards.

Bugs

 * 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.(comfirmed X-Box 360,PS3)
