Elliott Tercorien

Private Elliot Tercorien, serial number 3477809, is found abducted on Mothership Zeta in 2277.

Background
Tercorien was a doctor working in Washington, who was drafted into the army just prior to the Great War. Much to his dismay, he was shipped to Anchorage, Alaska, after receiving training in cryo science. Attached to the 108th Infantry Battalion, he and his team were responsible for patching up soldiers wounded in combat with the Chinese.

It was there that he and his medical team were abducted by Mothership Zeta. Only two other members of his squad survived the experiments when the Lone Wanderer arrives. They were kept frozen separately near what appears to be a surgery with the rest of his squad's bodies.

Relationships
His unit:
 * Sgt. Daniels (active)
 * Cpl. Rheems (K.I.A.)
 * Cpl. Spurlock (K.I.A.)
 * Pvt. Mears (K.I.A.)
 * Pvt. Dawkins (M.I.A.)
 * Pvt. Beckett (active)

Quests

 * Among the Stars: You have the option of bringing Elliot Tercorien with you as a companion to the Cryo Lab to help out. Elliot can either put the other two surviving members of his squad out of their misery or revive them. If they are revived, they only have a limited amount of time before they die.
 * This Galaxy Ain't Big Enough...: If Elliot survived his section in Among the Stars, he will help in the last battle by keeping aliens off you while you fight the other mothership.

Other interactions

 * If the Lone Wanderer has any alien biogel, Elliot has the ability to modify the regular biogel into adapted biogel. The adapted biogel has a much higher healing capability but still contains the either helpful or nasty side effects of regular alien biogel.
 * After taking him into the Cryo Lab, he will gain the ability to make cryo grenades and cryo mines. The first batch consists of 3 of each and can be taken after 1 hour. The player can then receive another 2 cryo grenades and 2 cryo mines every 3 hours. All conversation options which allow the player to request cryo mines and cryo grenades are only available while Elliot is in the Engineering Core section of Mothership Zeta.
 * It is still possible to get cryo mines and grenades after the space walk, by going through the teleporter after the Compression sequence and asking him to make some while in the Engineering Core.
 * After This Galaxy Ain't Big Enough... is completed, the player can return to the Mothership at any time and ask for weapons. If Elliot has some stockpiled, he will provide you with what he has in his cache. He gives either alien atomizers, alien disintegrators, or shock batons, and it is common that he will give multiple weapons at once. After giving away the weapons, the player will have to wait or return in another few hours for him to salvage more.

Effects of player actions

 * After the This Galaxy Ain't Big Enough... quest is completed, he remains aboard the Mothership, admitting he has got nowhere and nothing to return to. While he is onboard, he will continue to salvage alien weapons.

Inventory
* These weapons are given to Private Beckett and Sergeant Daniels.

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

Behind the scenes
When you ask him what the aliens want with Earth, he tends to get inconsistent, and will refer to multiple explanations for alien encounters from various sci-fi shows, such as Independence Day for the resource consuming theory and Star Trek, for his idea that the aliens seeded life on Earth, and even Invasion of the Body Snatchers for his idea of clones wanting to replace people on Earth.

Bugs

 * After reaching the command deck, his forehead may become transparent. If the player goes down to the Capital Wasteland and then back to the Mothership, his forehead will reappear.
 * Elliot may freeze after the time delayed death of Sgt. Daniels and Pvt. Beckett.
 * Elliot's AI in certain situations makes Elliot flee when any hostiles are nearby. Alien Workers are considered hostile towards the player and Elliot (even though they never attack) and if spotted by Elliot will cause him to flee. So you may find Elliot fleeing and unable to be spoken with. To fix this, just shoot him or kill the Alien Workers in the area and he'll snap out of it. Note that killing the Alien Workers also gives bad karma.
 * Elliot will suddenly stop making you Cryo Grenades/Mines, The Dialogue option will still be there but when asked about Cryo Grenades/Mines he will say "Not yet, Still working on them" The cause hasnt been identified and the only fix is to either Uninstall then Reinstall the DLC (Which can lead to more Bugs) Or loading a previous save point, This has only been confirmed on Xbox360
 * Elliot's AI causes Elliot to flee from anything hostile in some situations. This is fine the rest of the ship, but in rare cases in the bridge he will flee to the Engineering Deck and very rarely (after the finished quest) the Capital Wasteland. In the event of these happening, he will go missing and sometimes end up dead.
 * Elliot's voice acting also has a small bug in it. When walking near him, he might say "Oh... Hi.", but it is immediately followed by "wanna do that again?". There is clearly something missed while recording, as the "Oh... Hi" is subtitled, but the second part is not. The reason he asks, "Wanna do it again?" is most likely because he stammered slightly on the word "hi".
