Grady's Package

 is an unmarked quest in Fallout 3 which can be done alongside the Those! 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 located with directions below. 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 case. (B)

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 right 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)

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 loot it off his corpse after you've killed him, it will have been fully repaired. Alternatively, you can Mezz him before he takes it and get 200 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, (west of Jacko's Pop & Gas Stop and South-West of Smith Casey's Garage) he will reward you with 200 caps, or 300 if you pass a speech check.

Glitches

 * Sometimes when you get to Girdershade Ronald may not be there. If you then head NW you will encounter two Enclave Soldiers, an Enclave Officer and two Deathclaws out in the Wasteland.  The Enclave personnel are all lying on the floor - they appear dead, but once you've killed the Deathclaws you will be attacked by what seems to be 'invisible enemies'.  You are even given the opportunity to pick-pocket them if they happen to be close enough!  The only way to cease these attacks will be to shoot the three Enclave 'corpses' lying on the ground, until their health is completely depleted.
 * Sometimes if you give Lug-Nut the Naughty Nightwear and take it back, you will be unable to sell it to Ronald, as there will be dialog option for it. Of course this could not be a glitch, as technically you did give it to Lug-Nut and not Ronald.
