Brain Tank

The Courier's brain is the isolated, conscious, and interactive brain of the Courier.

Background
The Courier's brain is removed by the Think Tank of the Big Empty and subsequently forgotten about. Soon after, Dr. Mobius takes the opportunity to seize the brain and secretly take it away to his stronghold, the Forbidden Zone. The brain enjoys the peace and quiet of its new home, along with the relative safety and cleanliness, when compared to the wasteland.

Quests

 * Old World Blues: Get your brain back!

Appearances
The Courier's brain appears only in the Fallout: New Vegas add-on Old World Blues.

Bugs
After progressing through the dialogue with the Courier's brain the option to say "So, what, you'd rather just stay here? Never leaving that tank of... whatever that stuff is?" appears, however, if you choose it you will get stuck in a never ending speech loop. This also occurs on PC as well, specifically at the moment when the brain begins reminiscing about past feats by Courier. In the observed case, loop occurred between brain recalling Jason Bright`s departure and activation of Helios One. It seems that there are missing dialogue and sound files for the Courier's brain other than the two references toward Jason Bright and Helios One.
 * Workaround: to get out of dialogue loop, in console type (close all menus). This will exit the current dialogue with the brain tank, and allow players to walk away or enter dialogue again, but the loop will occur once more if same response is selected, so choose wisely.
 * The trigger to this bug is the line about Jason Bright. If the Courier does not complete Come Fly With Me prior to speaking with the brain, this bug will not occur.
 * This bug is still presented in PC v140525. There are quite a few talk-route to get past it, both straight-until-complete, and stop-and-talk-again. Should players fall into the route that lead to the bug, use the player.cam method above, then choose the line to negotiate with the brain. That is if reload the Auto save is not an option.
 * Reloading the game from a previous save is the best way to fix this on console.
