Senior Knight Lorenzo

 is a senior knight in the Brotherhood of Steel that is living in the Mojave Wasteland in 2281.

Background
Lorenzo is found in the Hidden Valley BoS bunker in a workshop room.

Interactions with the player character
After Elder McNamara reveals the delicate state of the air filtration system in the Hidden Valley Bunker, the Courier will be directed to Lorenzo. Initially, Lorenzo will express the guilt he feels. He reveals that the Courier is far from the first person that McNamara has told about this and that the previous groups sent out to retrieve the parts have never returned, and are presumed dead. Lorenzo blames himself for their deaths. After the Courier insists that they can handle the challenge, Lorenzo changes his tone, becoming slightly offended and saying that he won't be to blame when they die.

Upon the Courier's return with the parts, Lorenzo will be pleasantly surprised, feigning to have faith that you could complete the task.

Note
If you choose to assist Head Paladin Hardin to overthrow Elder McNamara, you will not be able to complete the air filtration system quest, if you've spoken to Lorenzo about the filtration system before Hardin takes over you can still turn in the parts to him, but McNamara will no longer have the completion dialog. If you do not speak to Lorenzo about the filtration system before Hardin takes over, you can still get the starter dialog from Lorenzo, but you will not get his dialog for turning in the parts even if you have all the parts in your possession.
