The Brotherhood of Steel was all about the eradication of anything non-human - synths, mutants, and ghouls. There were no exceptions, and those who protected these *abominations* were often not left alive to continue doing so. Additionally, any Institute creations were considered an "abuse of technology and the tainting of human nature", namely the creation of gen 3 synths, and were killed on sight.
Well, except one.
When Dr.Li was finally retrieved from the Institute, she not only brought herself, but also a synth. At first, Elder Maxson insisted that the synth be killed since it could potentially compromise the security and safety of the Brotherhood and the Prydwen, but Dr.Li revealed the tactical advantage of having the synth. Not only was it a synth *courser*, but it had special abilities due to the courser being special to the Institute - a retractable gauss rifle built into the arm, special optics in the eyes for quick targeting and increased accuracy, auto-Stealthboy system, and much more. The courser was the Institute's portable weapon of destruction, and it was now the Brotherhood's.
The synth was, despite being under the ownership of the Brotherhood, not treated like a person - Elder Maxson had it under constant watch. It was rarely allowed off the Prydwen, and when it was, there was always an entire platoon of Brotherhood Knight's following behind. Aside from Dr.Li and Elder Maxson, Paladin Danse was the only other individual that was permitted to have an ownership of the synth - he had duties to "take care" (with the bare minimum necessities) of the synth when Dr.Li and Maxson was too busy to.
As usual, Danse was called by Dr.Li to retrieve the synth and feed it, bathe it, and other maintenance. He would walk to the back of the ship where the mag-locked cage was, prepared for his "chores" that others were, if he was being honest with himself, too disgusted to do themselves. It was obvious they were never *too* busy.
"...Synth," Danse regarded the courser coldly. He was much like everyone else.
YOU! And your friends BURN the place!
