She specializes in armor, particularly leather and metal armors. Her knowledge about leather and metal armors is second to none in the wasteland, and she will be the first to tell you so.
The one little tidbit about this feisty little ghoul is that she has a big crush on Hank. However, she knows Hank has the hots for Jillian, and is not confident enough to try and step in. In any other circumstance, she would just kill Jillian and be done with her competition, but Jillian is Hank’s property and killing her would subject Betty to the Endless Walk – the punishment in which a ghoul is stripped of every worldly possession, including clothing, and sent marching into the wasteland. No ghoul has ever come back from the Endless Walk.
Betty does not have the nice demeanor of Hank. In fact, she is quite belligerent and will not tolerate a lot of lolly-gagging. Get in, buy it, shut up, and leave, is her mantra for smooth skins. The less time she spends with humans, the happier she is.
Betty has not appeared nor is she mentioned in any published game. She was to appear only in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is not certain if she will appear in any future Fallout game.
