When Picard is declared lost, Riker receives a field promotion to Captain. He chooses Shelby as first officer over Worf and Data and she is promoted to Commander.
39 starships and 11,000 Starfleet personnel were lost at Wolf 359, including Admiral Hansen and the U.S.S. Melbourne (Riker was offered command of the U.S.S. Melbourne NCC-62043 in Part I).
The Battle of Wolf 359 will be seen from Sisko's perspective in the Deep Space Nine pilot "Emissary".
This is the first time we've seen a saucer separation since season 1's "The Arsenal Of Freedom".
Data sends a "Sleep" command to the Borg collective; the malfunction causes the ship to self-destruct.
This episode was nominated for 4 Emmy Awards: it won Outstanding Sound Editing and Outstanding Sound Mixing, and was also nominated for Outstanding Special Effects and Outstanding Art Direction.
Wolf 359 is an actual star 7.6 light years away and the third closest star system to our solar system. (The first two are Alpha Centauri and Barnard's Star.)

While the Enterprise undergoes repairs at McKinley Station in orbit around Earth, Picard returns home to visit his brother Robert in France. Worf’s adoptive parents, Helena and Sergei Rozhenko, visit the Enterprise. Wesley receives a holographic message from his late father, Jack Crusher.

The Enterprise is docked at McKinley Station for six weeks for repairs because of the Borg attack. During this time a defective hatch is installed on the Enterprise's warp drive dilithium chamber, which causes a serious failure several months later (see "The Drumhead").
O'Brien is given a first and middle name, Miles Edward, in this episode. Sergei Rozhenko calls O'Brien a non-commissioned crewman, though he clearly is wearing a Lieutenant's two solid pips (the same as Worf, who is standing right next to him). This changes in Season 6, when he is "demoted" to Chief Petty Officer (see "Realm of Fear").
David Tristin Birkin later plays the young Jean-Luc Picard in 6th season's "Rascals".
This episode is often shown out of order during reruns with the next two episodes due to their production numbers.
This episode has no shots on the main bridge.

Dr. Soong calls Data back to give him a chip that contains memories and emotion subroutines. Lore fatally injures Dr. Soong and steals the emotion chip.
This is the first time Data meets his "father" face to face. It was previously thought that Dr. Soong was killed by the Crystalline Entity (see "Silicon Avatar").
Data gets the emotion chip back in the 7th season opener "Descent, Part II", and finally installs it in Star Trek Generations. In the meantime, the chip's appearance would change from the tiny round disc seen here to resemble a large "Chex" cereal look.
Lore was floating in space for 2 years until he was found by a group of Pakleds. He was found wearing a Pakled outfit. (See "Datalore" and "Samaritan Snare".)

When she beams aboard to meet with Captain Picard, she brings a surprise for Lt. Worf -- her young son, who is also Worf's son. While Worf is faced with conflicting feelings for K'Ehleyr and his child, Picard must confront a momentous task. Klingon High Council Leader K'Mpec has been poisoned and is on his deathbed. Knowing he doesn't have long to live, he summons Picard to arbitrate the imminent power struggle for leadership of the Klingons. One of the two contenders is also K'Mpec's murderer, and the fragile peace between the Federation and the Klingons depends on Picard's ability to discover who is the traitor -- before he becomes the new Klingon leader.

The Klingon storyline continues in the season finale "Redemption, Part I", where Gowron is officially installed as Chancellor of the Klingon Empire.

Deborah Taylor (Capt. Chantal R. Zaheva)
The model for the U.S.S. Brattain NCC-21166 had the name incorrectly spelled as Brittain (it was spelled "Brattain" in the computer displays, the script, and the closed captioning). The model was a modification of the U.S.S. Reliant NCC-1864 from Star Trek: The Wrath of Khan (both were Miranda-class starships).
Deanna's nightmare has a voice telling her "Eyes in the dark...One moon circles." The dream is a telepathic message from a ship trapped on the other side of the rift. The message refers to the binary star system and that they need Hydrogen. Deanna saves the day when she tells the ship trapped on the other side "NOW" in her dream as Data releases Hydrogen. The resulting explosion blows the two ships free.
This episode gives us our first peek at "The Fueding O'Briens" who will make an artform out of arguing on Deep Space Nine.

Admiral Satie accuses Picard of consorting with the Romulans and states that he has violated the Prime Directive 9 times since taking command of the Enterprise.

The faulty hatch on the dilithium chamber was installed while the Enterprise was docked for repairs during the episode "Family".
The Enterprise transported the Romulan spy in the episode "Data's Day".
Satie directly contributes the destruction at Wolf 359 to Picard, 39 starships destroyed and nearly 11,000 lives lost ("The Best of Both Worlds, Part II"). This sentiment is echoed by Benjamin Sisko in the Deep Space Nine pilot episode "Emissary".

Robert Harper (Lathal Bine)
Odan is mediating a dispute between the Alpha and Beta moons of Pelia Zel.
This episode introduces the Trill "joined species," the species of Lt. Dax of Deep Space Nine. However, they seem to be very different species. Odan has ridges on his forehead, while Dax and every other Trill has spots. Odan says a transporter will damage the Symbiont, while Dax transports all the time. Odan implies that all of the Trill are "joined," but in the DS9 Trill, only 10% of the Trill are joined. Odan's symbiont also seems fond of pushing out on his abdomen. We have never seen this in any of the DS9 Trills. The symbiont here completely takes over the host's mind. In DS9, the symbiont combines with the host to create a new individual. In this episode, Troi and Picard claim they know little of the Trill. However, Dax is a Starfleet officer, and her former host Curzon Dax served with Sisko and they were very good friends. Trill is a Federation world. The DS9 producers said they made the changes to make the Trill more practical.
The replacement host sent by the Trill is a female. Beverly admits that she loves Odan, but can not cope with this kind of change, despite Odan's wishes to continue seeing her. (In the modified Trill species, a relationship with a previous host's lover is forbidden; the punishment is exile, with the eventual death of the symbiont when the host dies.)
Troi and Crusher are seen taking advantage of the ship's salon, which has a new Bolian barber.
