Somah is one of the few wastelanders unfortunate enough to have stumbled across recon craftTheta and been abducted. Prior to this, she was a slaver working in conjunction with the slavers at Paradise Falls. She has a sweet, calm disposition that is undercut by a sadistic streak that shows through when she's under stress. She's used to being in charge, but is aware that she's out of her depth aboard the alien ship. Aside from providing supporting fire, she can repair any items that may need fixing.
After completing Not of This World and reaching the Engineering Core, she will Repair the player's items, but insists she be paid for her services. Somah's repair skill is based on the player's level and reaches 100 at player level 15, giving her the highest non-player character repair skill in the entire game at that point.
In the Engineering Core, Elliot may ask her what has happened since he was abducted. When he shows distress at her news of the Great War, she tells him to "suck it up and deal with it like the rest of us".
Once you reach the cryo-chambers she will rejoin you and now be equipped with a combat shotgun. There is no telling where she picked this up.
While she refuses to comment on where in the Wastelands she hails from, when exploring the robotic assembly line she lets slip: "These assembly lines remind me of the pens we kept our sl... (pointed) I mean our prisoners in."
If one manages to disarm an alien in the first few minutes of the DLC, she may pick up the weapon, provided that she does not have her combat shotgun with her yet.
pcxbox360ps3 Dialogue options exist to learn of Somah's past by passing a speech check, using the Lady Killer perk or passing an easier speech check if you found Alien captive recorded log 22. However, these conversation choices are not displayed in the game, as the options are mistakenly set to run all inventory, skill, and perk checks on Somah rather than the player. [verified]
