Crow used to be a tribal shaman and his spiritual views on the wasteland can seem odd to the others - especially when they're mixed with his uncanny sense for selling armor. There are rumors that he came from Oasis, but if he did, he never talks about it.
Merchant Empire: If you fully invest in his business, you will receive Crow's eyebot helmet from him as a gift of gratitude. This will also increase his Repair skill to 65, allowing him to repair items to a max of 79%.
Crow's pack brahmin has a significantly higher amount of health than all other merchant's brahmin.
If Crow is killed his pack brahmin may do any of the following: wait outside the entrance of Rivet City, wait ouside of Canterbury Commons, wander around in the manner of a mad brahmin, stay by or follow Crow's corpse if you drag it or continue to follow the trade route. This also happens if the pack brahmin is killed and Crow survives, just the roles are reversed.
Agatha is friends with Crow, and mentions him on her radio station. He is one of the merchants that goes to Agatha's house to trade supplies. Although Agatha has nothing really to trade (as you can see by her house & the location of it). When you talk to her, she mentions that instead of trading items, she actually plays Crow songs on her Home-Made Violin in return for the supplies she needs.
