At the end of the episode, Geordi walks into Data's quarters on the Enterprise, and, after pleasantries are exchanged, Geordi asks about the tiny "emotion chip" which Data is holding, after having removed it from Lore's presumably disassembled body. Data says that the chip is damaged and no longer functions, and prepares to disintegrate it using his phaser. If it doesn't work, why bother disintegrating it? Wouldn't the phaser fire trigger a security alarm, as it did in the movie Star Trek VI: The Undiscovered Country, as well as in other Next Generation episodes? Alternately, Data could have simply thrown it out in whatever passes for futuristic garbage pails or snapped the chip in two or more pieces.
Toward the end of the episode, Lore runs to his inner sanctum, presumably to plot an escape, when Data rushes in, gun in hand. Lore turns to look at Data, and says, "You should be careful with that, brother . . . you could hurt someone." However, Data's weapon is pointed down to the ground, not at Lore.
Geordi has been given the first of a series of brain-disintegrating "probes" which stick out of his head. Upon being returned to the prison cell, Geordi is put on a table, clearly uncomfortable, when the alleged empath, Troi, asks, "Are you in pain?" She can sense emotions from Data, the android, but not the human Geordi? Prior episodes made it clear that "strong-willed" beings can't be read by Betazoids, but Geordi wears his emotions on his sleeve, so she shouldn't have had any such difficulties.
Troi shouldn't sense anything from Data at all, emotions or not. Her abilities are a low level form of telepathy (a cut down version of a full betazoid). In "Tin Man," Elbran stated that he could not read Data at all. This is coming from probably the most powerful Betazoid in existence. If Elbran couldn't read Data's thoughts which are nothing more than computer equations, then a far less powerful Troi certainly shouldn't be able to sense his emotions which would also be nothing more than mere computer equations as well.
If Lore is a sentient being, then shouldn't he get a trial before being deactivated? And didn't Picard say in "Justice" that the Federation did not believe in capital punishment?
When Data and Lore talk on the veranda in the bright daylight, the shadows are all messed up. Data's shadows point to the right while Lore's point to the left.
They fire a particle beam to excite the star and destroy the Borg ship. Although previous episodes have established the paricle beam is emitted from the tractor array, here we see an exterior shot seeing it come from the forward phaser section.
In "I Borg" the Enterprise hid in a star's chromosphere with ease. Here they make a big deal out of hiding in a star's corona, which is further from a star's core (and thus less dangerous) then the chromosphere.
The emotion chip looks substantially different from what we saw of it in "Brothers" - there it was a metal sphere and here it is a flat disk with a wedge cut out of it.
When Data and Lore are talking outside, Data visibly squints in the sunlight. This despite the fact that Data's eyes allow him to stare directly into bright lights without flinching (see "Timescape" for one example).
In the first part of this episode, Deanna told Data that emotions are neither positive or negative. However here she says all she is sensing from Data are negative emotions.
Response: Although the Borg function as a Collective, not every Borg in the universe is linked at all times. Hugh caused pandemonium when he returned to his ship, but because of the disorientation, those Borg never returned to cause mayhem in the full Collective.
Lore: The reign of biological life-forms is at an end. You, Picard, and those like you are obsolete.
Troi: Data, all I am sensing from you is anger and hatred. Have you felt any other emotions?
Data: There are no other emotions.
Injoke: Dr. Crusher tells Lt. Barnaby to check the Enterprise's records for an entry on metaphasic shielding. James Horan (Barnaby) also played the character (Dr. Jo'Bril) who tried to steal that invention in the episode "Suspicions."
This episode marks the final appearances of Lore (Brent Spiner) and Hugh (Jonathan Del Arco).
This would mark the Borg's last appearance until Star Trek: First Contact.
Early draft featured Data killing Lore and Lt. Barclay.
