Future Imperfect

 is a Fallout 3 quest and the final of the flashbacks. For completing this quest, you get The G.O.A.T. Whisperer which is a Achievement on the Xbox 360 and PC; and a Bronze Trophy On the PlayStation 3.

Walkthrough
The quest starts after a talk with your Dad, during which you're told you have to go to class and take the G.O.A.T. test. Bobblehead - Medicine is on his desk; this is one of only four opportunities to take it. Just outside the classroom, Amata is being harassed by Butch DeLoria and his gang, the Tunnel Snakes. There are a variety of choices that can be taken here.

The player may pass a speech check warning Butch that the Overseer will come down on the Tunnel Snakes if he continues his actions. This will earn good Karma. Also for good Karma, Wally Mack may be convinced that he is being used by Butch as a lackey, which causes him and Paul Hannon to leave the group. More good karmatic options include Butch being told off, or fighting Butch and his gang. If the lattermost is chosen, then once the player or Butch is reduced to 50% health, the fight will stop (alternatively you can start the fight and run into the class room. This will stop the fight and still give you good karma). The only bad karmatic option here is telling Butch that Amata is sensitive about her weight, giving him more ideas to make fun of her. Wally Mack may still be convinced to leave Butch's gang after doing this. Alternatively, the player may ignore the incident completely for no change in Karma. Keep in mind that the path you take here will determine your initial karma levels in the game, and it will be very difficult to change your alignment afterwards (the karma shift is quite high).

Mr. Brotch will approach the player as they enter. If asked whether you really have to take the test, he will allow you to skip it, and select your tag skills directly. The player may also ask Mr. Brotch to fill out the G.O.A.T, whereupon he will ask what the player likes and will assign tag skills accordingly. This won't earn the achievement, though. Otherwise, the player is to sit down at a desk, after which the G.O.A.T will begin. See the G.O.A.T article for information on the questions and how how the answers given influence the results. If the tag skills given are undesired, they may be changed by speaking with Mr. Brotch after the test.

Walking out of the classroom after setting your tag skills will move the game onto the next quest.

Behind the scenes
Also, an episode of Star Trek: The Next Generation titled "Future Imperfect" features Commander Riker, who has aged 16 years; the same age as the lone wanderer at this point of the game.
 * The quest's name derives from the "future imperfect" tense, which describes ongoing action in the future: "I will be running."

Bugs

 * The test may fail to begin after the player sits in a desk. Some students may be scribbling some answers on their papers but nothing else will happen, requiring a reload.
 * Mr. Brotch may not address the player after entering the classroom. This may happen if you have knocked out more than one of the Tunnel Snakes in the hallway when they were teasing Amata.
 * After the blinding light appears right before the quest begins, you can see your father examining you, but he has stretched and bent fingers.
 * If you knock out all the tunnel snakes and sit in the last seat on the right and right when the test starts you can get up and leave the room to skip the test.
 * If your female character has the "Frazzled" hairstyle it will be replaced by the "Pretty Puff" style for the duration of this quest.
