Glenn began his career as a junior scout. He was one of the original team members who began to explore the east with Andrea Brixley. He found his superior to be very confident in the wilds and he learned a lot from her. He soon began to hold her in the highest respect and this eventually turned to love. However, Andrea's promotion to commander placed him in an awkward position and he has steadfastly refused to confess his feelings for her.
Glenn is very dedicated and loyal. He has a laid back personality and rarely allows anything to upset him. He is a hard worker and oversees the basic functioning of the base and its personnel. He also recognizes his commander's lack of organizational abilities and discretely handles anything that she overlooks or forgets.
Glenn Deering has not appeared nor is he mentioned in any published game. He was to appear only in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is not certain if he will appear in any future Fallout game.
