History Recap / StarTrekTheNextGenerationS4E3Brothers

* AndIMustScream: Discussed. Lore says he spent two years floating in space after his last encounter with Data and would still be out there if not for a passing Pakled ship.

* BorrowedBiometricBypass: After Data has locked the ''Enterprise'' crew out of every system - including the transporter - they network some tricorders together to convince the transporter that it is beaming the last person it transporter - namely Commander Data - to the surface when they beam Worf, Riker, and LaForge to Soong's home.

* YoungerThanTheyLook: Possibly if what Dr. Ira Graves said about being Soong's mentor was true. Graves, while still old looking, didn't look anywhere as ancient as Soong does. This might be chalked up to makeup artists overdoing it when a younger actor is made up to play an elderly character.

* EasilyForgiven: Soong doesn't hold the destruction of Omicron Theta against Lore, even after Data tells him what happened. When Lore fatally wounds him and steals the emotion chip, Soong doesn't seem mad, just sad and disappointed.

* AdvancingWallOfDoom: During his trek from the bridge to the transporter room, Data at one point initiates a "cascade sequence" with the forcefields that causes the one ahead of him to jump ahead by a few inches every few moments, in effect creating a moving wall that forces the security officers attempting to stop him to retreat.

* CuttingTheKnot: When he's intercepted at the transporter pad, Data simply has the computer erect a forcefield around the pad and then uses a site-to-site transport to get to the planet below.

* AmnesiaDanger: Much of the drama in the second half revolves around Data not remembering that he locked out the ''Enterprise'' while he traveled to meet Soong, being unaware until Riker finally catches up with him. Had he known this he likely would have immediately returned to the ship, or at least gotten Soong to get their business over with as fast as possible.

* SelfServingMemory: Soong and Data call out Lore on this. Data is not a "less perfect" android, they are both nearly identical in construction, just programmed differently. And the colonists on Omicron Theta were not "jealous" of Lore, they were afraid of him.
* SiblingRivalry: During their family reunion, Data is deeply affected when Soong asserts that he is not inferior to Lore (as Lore had previously claimed) and that they are in fact almost identical except for their programming. Lore feels that he was TheUnfavorite given that Dr. Soong decided to move on and build Data rather than focusing on fixing Lore's personality disorders. He tricks Soong into giving him the emotion chip intended for Data by impersonating him.

* ThePasswordIsAlwaysSwordfish: Subverted. Data creates an insanely long password to keep the crew of the ''Enterprise'' from regaining control of the ship. The password is equivalent to a 269-bit key in symmetric cryptography which is impossible to break. The crew is unable to guess the password or even how long the password is and is stuck until Data returns and unlocks the computers.

** Data is able to seize absolute control of the ship's computer by virtue of the fact that, having sophisticated speech capabilities, he can ''precisely'' mimic Picard's vocal patterns and fool the voice biometrics authentication that the computer uses. This is in spite of the fact that the computer tracks the location of all members of the crew in real time, and thus must be aware that Picard is not on the bridge even though he's supposedly issuing orders from that location [[note]] Data using the ''Science I'' console on the bridge may have been meant to imply that he was tampering with the internal sensors in some way, but this is never addressed on-screen or in the script[[/note]]. A simple retinal or facial recognition scan would have foiled or at least seriously hindered Data's efforts. It's really unsettling just how easily one android hijacks the entire ''Enterprise'', and none of the security holes this reveals are ever mentioned following this or shown to be fixed.

[[caption-width-right:350:Data (played by Brent Spiner) meets Dr. Noonien Soong ([[ActingForTwo played by Brent Spiner]]), before they're joined by Lore ([[RuleOfThree played by Brent Spiner]]).]]

* CrazyPrepared: Dr. Soong survived the Crystalline Entity because he always has an escape route prepared just in case. This becomes FridgeBrilliance after we encounter his ancestor in ''Series/StarTrekEnterprise'', imprisoned for his own controversial research and with a habit of escaping as a hobby.

* SwissCheeseSecurity: {{Averted}}, given the extensive effort and skill Data requires to hijack the ''Enterprise''. At the same time, some basic safeguards are overlooked, such as the computer accepting commands from "Picard" on the bridge when it knows for a fact he's in Main Engineering. Pay attention, ''Voyager''...

the ''Enterprise'' is on a medical mission to transport a sick child to a starbase medical lab after a prank from the boy's brother went awry. While escorting the older boy to pay his sick brother a visit, Data begins acting oddly. Without warning, he turns off the life-support systems on the bridge, forcing the rest of the crew to evacuate. He then commandeers the ship by imitating Picard's voice and setting security codes so that only he can control all the crucial systems, then sets a new course to an unknown planet.

The crew is unable to regain control, but when they arrive at their destination, they discover that he was acting under compulsion. Data has an implanted homing device that was activated by his creator, Dr. Noonien Soong, who was thought to be dead. Dr. Soong has a gift for Data: a chip he's perfected that will give Data human emotions. However, when he activated the homing device, he also unintentionally summoned Data's "brother" Lore, who decides he wants the chip for himself.
