Matthew (Fallout 2)

Matt is the Brotherhood of Steel agent staffing the San Francisco outpost of the BOS around 2241.

He gave the quest about Vertibird plans to The Chosen One when he met. If The Chosen One completed the task, Matt eventually killed by the Enclave's own Frank Horrigan in 2 days.(It has not confirmed what was Chosen One's choics, or Matt is dead or alive in Fallout canon)

Interactions with the player character
Somehow, he knows the Chosen One's name even before they first meet. He wants the Chosen One to get the vertibird plans for the Brotherhood of Steel and will put Navarro on the map.

The Chosen One also gets to keep the original plans for use with the other quests from the Hubologists and the Shi. Two days after this Matthew will disappear, and accessing the ACE computer in the bunker will reveal what happened to him.
