Ness

Ness is a treasure hunter currently operating in The Commonwealth in 2287 in Fallout 4.

Other interactions
The meeting with Ness is a random encounter and therefore can occur anywhere, though it is more likely on roads.

Ness may hire the Sole Survivor as a mercenary to clear Skylanes Flight 1981 of raiders in the quest Meet Ness at the Crash Site, offering to split the loot. She can be persuaded to increase the amount of caps she rewards. Upon questioning her further about what her real intentions are, she may reveal she has been scavenging Skylanes flight wrecks for years as the company was involved in illegal smuggling operations before the Great War.

Appearances
Ness appears only in Fallout 4.

Bugs

 * Ness might get pulled into the "Quick test cell" limbo and will become hostile with other characters in this box with her. Any non-essential NPC may be killed.
 * Upon looting the hidden compartment in Skylanes Flight 1981 while clearing the site of raiders, Ness may become hostile.
 * When helping her clean the plane from monsters, if you leave her waiting to finish a quest then come back later, she will not initiate dialogue again even though the quest marker still marks her supposed location. Pickpocketing and reading Ness' lead note from her may resolve this issue, though this may not work on PC.
 * Ness may become hostile to any nearby settlers and provisioners, making it difficult or impossible to trigger the quest as dialogue cannot be initiated. Since Ness, settlers and provisioners are all essential there will be no casualties, and they may go separate ways after a few minutes.
 * If a companion is dismissed at a crash site, the companion may become hostile towards Ness and any other Gunners nearby.
