Scribe Bigsley

 is a scribe of the Capital Wasteland Brotherhood of Steel who is added to Fallout 3 in the add-on Broken Steel.

Background
Bigsley's personality is that of an overworked genius with little patience for those he feels have not earned their status. He constantly belittles and insults everyone around him, both his initiates and the Lone Wanderer. While it might be assumed that this is because managing the Purifier and water distribution has placed him under excessive stress, talking to him reveals that he was kicked out of all three orders, after (he claims) the lead Scribe of each order felt threatened by his ability and intellect.

For example, his modified Laser Rifles resulted in the wounding of some initiates (due to the initiates' inability to handle the extra power output). After being transferred to the Order of the Shield, he antagonized Scribe Bowditch by calling the latter's theories outdated. He was then transferred to the Order of the Scrolls, where he quickly ran afoul with Scribe Jameson (who previously condemned Scribe Yearling to a life-threatening assignment at the Arlington Library for similar reasons). He also, like many others, questions Elder Lyons. In the end, he even felt that he had lost the support of Scribe Rothchild, who transferred him to the Purifier project, an assignment Bigsley feels is akin to exile.

Effects of player actions
Once the Purifier has been activated, Bigsley and several neophyte scribes take up residence at the Jefferson Memorial. They work on solving the problem of delivering the processed fresh water around the Capital Wasteland and provide the player with the side quests of Broken Steel, all related to the water problem. Holy Water and Protecting The Water Way and their rewards are obtained by talking to him, while The Amazing Aqua Cura can be obtained through a speech check, by hacking his computer, or with low enough karma.
