Somah

 is an abducted slaver in the Fallout 3 add-on Mothership Zeta in the year 2277

Background
Somah was a slaver, looking to scavenge something good from the crashed UFO by following the signal. Instead, she's now just another captive for the aliens' experiments.

Effects of player actions
She is located in the same cell you are in when you wake up after the aliens abduct you. She can't tell you much, but does have a plan to escape: she suggests that the aliens want all the humans alive, so they'll just have to fake a fight to make it look like one of them will die. After hitting eachother for a while, two aliens will come to the cell door. At this point, Somah becomes a friendly character again and joins the player in their fight against the alien captors.

After reaching the Engineering Core and completing Not of This World, she can Repair your items (up to 100%!), insisting you pay her for her services. Additionally, Somah is the companion from the group able to assist you in destroying the generator in the Robot Assembly area.

Appearances
appears only in the Fallout 3 add-on Mothership Zeta.

Bugs

 * In some cases, Somah's repair skill starts off at 100, in other cases 75.
 * While you are fighting the hostile aliens on the ship's bridge, Somah goes down after a serious hit by the enemy ship. While she is down, you have an option to talk to her. When you select it, you will be able to loot her body (essentially pickpocketing her with a 100% chance of success).
 * After you've completed your spacewalk and passed through the second airlock, Somah and everyone else will join you (via teleporter). Sometimes Somah's forehead will be transparent and you can see only her eyes and hair.
 * Somah has been known to set off player placed mines, while the others do not appear to do so.
 * It is actually possible 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 recording 22. However, due to a bug, these conversation choices are not displayed in the game.
