Wahl is a convicted counterfeiter and a welder. Because Wahl shot a New California Republic soldier/hostage during a prison escape, his hand was smashed, branded, and his trigger finger cut-off. He's totally pissed at the NCR and wants to get what's in the Box (he thinks it's worth a lot) just to have a crowning achievement over them. He still welds pretty well, and always wears thick gloves. he wants everyone to leave Denver so he can go back and get the "big treasure".
