Unwelcome Discovery (不吉な予感! ブルマが知らせたミステリー Fukitsu na Yokan! Buruma ga Siraseta Misuteri) is the fourteenth episode of the Androids Saga and the one hundred thirty-ninth overall episode in the uncut Dragon Ball Z series. The episode first aired on May 13, 1992. Its original American air date was October 3, 2000.
Goku, Chi-Chi, Krillin, Yamcha, Gohan and Future Trunks are all in an airplane flying to Kame House to hide Goku from the Androids. Gohan asks Future Trunks if killing the Androids in the present will make the Androids of the future vanish, and Future Trunks realizes with much disappointment that his timeline is like a parallel timeline, unaffected by what he changes in this timeline.
At Kame House, Chiaotzu is cooking for Master Roshi and Oolong. After Master Roshi eats the soup he asks Chiaotzu how he can cook like that. Chiaotzu says he cooks for Tien Shinhan all the time while they train. Master Roshi decides to train Chiaotzu, though really just wants Chiaotzu to keep cooking for him. Next, Tien walks in the door, and he and Chiaotzu go off to train more for the Androids.
Meanwhile, Vegeta stands out in the rain on top of a small, rocky hill. He thinks about how Android 18 nearly killed him as her taunting words ring through his mind. Then, he flies into a wild rage and turns into a Super Saiyan. He begins talking to himself about how he is Super Saiyan and as one, he should have not been beaten by the androids. He says to himself that there must be a higher level of strength that a Saiyan can achieve other than Super Saiyan. Finally, he makes up his mind that he will work tirelessly to achieve this higher level by saying "I will be legendary!"
Back in the plane, Future Trunks is realizing that his time cannot be affected by the outcome of the time he is in now. He then has a flashback, and says he came back because Future Bulma wanted him to, and because he wanted to help the people in his time. The flashback shows Future Trunks walking down a street. Krillin talks to Bulma, and she sends him a picture of Future Trunks' Time Machine. However, it is old and covered in moss. The episode ends, and the preview for the next episode shows Gohan and Future Trunks finding an egg in the Time Machine.

Differences from the manga
- Chiaotzu cooking a meal for Master Roshi, Oolong and Turtle at Kame House prior to Tien picking up to go train is exclusive to the anime.
- Future Trunks remembering a talk with his mother and the terrorised wasteland that is his home is exclusive to the anime.
- Goku having a nightmare where he the Androids confront him and kill Future Trunks and himself is exclusive to the anime.
- Goku has a dream about Android 17 and Android 18, despite the fact that he has never actually seen either of them, nor would he know about the Lucky Foods van they arrive in. However, after Goku drank the Ultra Divine Water, he had visions of the future and a clear understanding of things, implying that he had developed some level of psychic ability. Furthermore, after training in 100x gravity while traveling to Namek, he had developed deeper psychic abilities as shown when he read Krillin's mind after his arrival there. In the TV special Bardock: The Father of Goku, Bardock implies that he feels psychic ability within Goku with lines like "You see it too, don't you?" For all of these reasons, it is perfectly reasonable for Goku to have psychic foresight within his dreams.
- In the original dub, the "Goku's Nightmare" theme is playing when Goku has a nightmare about the Androids, followed by a bit of "Ginyu Transformation" etc. In the remastered version, the music is replaced with "Goku's Dream".
- Interestingly, Goku's Dream is the one of two times that Android 17 is actually seen using the Gun he carries around in his holster. The second is Free the Future against an old man.
- The Lucky Foods van says "campany" instead of "company". This is due to Japanese pronunciations not including an "uh" sound, as heard in the word "company." Rather, Japanese uses the "ah" sound, pronouncing "company" like "cahmpany," which is why misspelling it as "campany" is an easy translation mistake to make.
- In the flashback where he is walking down the street, Future Trunks' eyebrows are blonde instead of lavender.
- The ring tone for the phone that Krillin uses to call Bulma is the theme of Dr. Slump.
