The Enterprise responds to a request for medical assistance from Dr. Ira Graves, considered by many to be the greatest living mind in the universe. Graves didn't want any help. The Enterprise was summoned by his assistant, Kareen. Graves, a crotchety old man who doesn't really like people, is now in the terminal stage of an illness. Having taught Data's creator, Dr. Soong, everything he knows, he fancies himself Data's grandfather. Knowing his end is near, he transfers all of his knowledge and intellect into Data. As a result, Data begins to act irrationally, becoming a cause of concern to Picard and others. Written by garykmcd/edited by statmanjeff

Did You Know?


When Data refers to Wesley Crusher's "childlike mind," Wesley responds by saying "Data, chronologically you're not much older than I am." It is established that Data was constructed in the year 2336. As this episode takes place in 2365, it would make Data twenty-nine, which is at least twelve years older than Wesley. See more »

Lt. Cmdr. Data: I have noticed, Grandpa, that you keep repeating the same notes of a musical phrase I am unfamiliar with.
Dr. Ira Graves: Oh, it's a, it's an ancient little tune called "If I Only Had a Heart" - a plaintive lament sung by a mechanical man who longs to be human. It's his only wish.

Visiting Grandpa
14 December 2017 | by bkoganbingSee all my reviews

The Enterprise answers a distress call from Barbara Alyn Woods who is the late life trophy companion of Dr. Ira Graves played here by William Morgan Sheppard a curmudgeonly iconoclast. Patrick Stewart beams down Worf, Data, and a member of the medical staff Suzie Plakson who is a Vulcan. It is determined that the old iconoclast is suffering from an irreversible and fatal disease.

I did love the way each of the Enterprise away team reacted to the surroundings. When the isolated Ms. Woods calls Worf a Romulan, Michael Dorn holds that Klingon temper and makes allowances. Plakson whose Vulcan logical ways makes her just totally immune to Sheppard's barbs. I would love to have seen more of her.

However when Brent Spiner learns that Sheppard mentored Dr. Sung who built him and his twin he starts referring to him as Grandpa. And Sheppard has a plan to stick around after his physical body dies and it involved Brent Spiner.

Let's say that Sheppard's personality and social skills don't wear well on Data in every sense of the word.

Nicely done TNG story.
