Grouse

Grouse is a slaver at Paradise Falls who carries a Mesmetron weapon which can be obtained by killing him or by accepting the quest Strictly Business from him.

He is equipped with a Chinese Assault Rifle and Merc Troublemaker Outfit.

Strictly Business
Grouse mentions Eulogy Jones wants to acquire some VIP targets. If you accept his proposal to capture some slaves he will give you a list of some priority targets.

The targets are as follows:
 * Flak from Rivet City
 * Red from Big Town
 * Susan Lancaster from Tenpenny Tower
 * Arkansas from Minefield

You can ask him why these targets have been selected and his gives a brief explanation to add to the overall story line. Flak and Susan Lancaster were former slavers and Eulogy Jones wants them back. Arkansas apparently killed a crew of Paradise Falls Slavers and they want their revenge and Red made some promises she never kept and now they want to collect.

Unmarked quest: Strictly Profitable
After completion of Strictly Business you can continue to enslave random people and he will pay you for it.

Appearances
appears only in Fallout 3.
