Spock's father Sarek, the legendary Vulcan ambassador, now remarried to another Earth-woman, Perrin, boards the Enterprise to crown his career -before retiring - by finalizing painstakingly prepared peace negotiations with the Legarans. His chief of staff and personal assistant asked Sarek to be given maximal rest in view of his weak health, but he insists on attending the ship's Mozart concert starring Data as violin soloist in his honor, and is seen there to cry, unknown for a Vulcan. Over the next several days more crew members display unprovoked aggression, even toward friends and relatives. Data gets an entourage member to confirm a medical theory: Sarek is affected by the rare Bendii Syndrome, which causes old Vulcans to lose their most-prized emotional self-control, and telepathically spreads the epidemic. Picard must think of the negotiations with the probably susceptible Legarians, which cannot be delayed, while Sarek denies his condition, alas tellingly emotionally; once he ...

Did You Know?


Director Les Landau filmed Picard's outburst while moving the camera around him starting from his left and finishing on his right. Because the shot was filmed several times in a single take, Patrick Stewart had to do the heavily emotional scene several times in its entirety as well. See more »


After Commander Riker walks in on Geordi and Wesley fighting in the Legaran conference room, Wesley asks "May I be excused, Commander?", and immediately walks out of the room without any acknowledgment of approval from either Riker or Geordi to be excused. See more »

Wesley Crusher: Are the Legarans really gonna sit in this stuff?
Lt. Commander Geordi La Forge: Well, I'm sure not.
Wesley Crusher: Can you believe this smell?
Lt. Commander Geordi La Forge: What smell? What can I say, to us, it's a slime pit, but to them, it's home.

Sarek...the emotional menace!
17 November 2014 | by MartinHaferSee all my reviews

"Sarek" marks the second to last appearance by Mark Lenard as this Vulcan character. A year later he'd reprise the role in "Star Trek VI: The Undiscovered Country" and Lenard would die a few years later. Interestingly, later the character would reappear--with Ben Cross playing him in the reboot of the series, "Star Trek" (2009).

When the ancient ambassador arrives on the Enterprise for some important negotiations, the Captain is surprised at Sarek's handlers. Despite his looking amazingly good for a being over 200, his wife and assistant treat him as if he's very frail and are protecting him from others. Why? At the same time, strange things begin happening on the ship. Crew members start acting VERY emotional towards each other-- with angry outbursts, near fights and worse. Could it be that Sarek is somehow responsible for this? And, if so, how?! And, how can they hold an important conference is Sarek makes those around him enraged?!

All in all, a very sad episode of the series, as you see a beloved character succumbing to the sad effects of aging. Now I am NOT complaining about this--it is good to talk about dementias and other types of geriatric illnesses. But it is still quite sad. Well worth seeing.

By the way, Picard makes a brief comment that made me take notice. He indicated that he'd briefly met Sarek before...at his (Sarek's) son's wedding! Did this mean that Spock marries or that he has a sibling who married? I am sure the real die-hard Trekkies could answer this one.
