Patrick Stewart ... Capt. Jean-Luc Picard
Jonathan Frakes ... Cmdr. William Riker
LeVar Burton ... Lt. Cmdr. Geordi La Forge

After a human colony is attacked, Data assists Dr. Kila Marr in studying the life-form responsible. The crew attempts to locate and communicate with this huge creature - a crystalline entity which destroys by sucking off all carbon-based life from the surface of planets it encounters. Because her son Renny was killed in an attack years earlier, Dr. Marr's agenda may not be on the same page as the crew's. Written by Good2Go

Did You Know?


This is one of the few occasions Data demonstrates his ability to precisely mimic the speech patterns of other individuals. Other examples include Star Trek: The Next Generation: Encounter at Farpoint (1987) where he repeats Q's depiction of the trial against humanity, Star Trek: The Next Generation: Brothers (1990) where he employs Captain Picard's voice authorization codes to commandeer the main bridge, and Star Trek: The Next Generation: Descent, Part II (1993) where he mimics Captain Picard's voice to toy with Geordi.

When Data and Dr. Marr enter the turbo lift, and Data explains how the memories of the colonists have been transferred into his memory cells, Dr. Marr says, "Bridge." A few moments later when they arrive at the bridge and the turbo lift doors open, you can clearly see the same corridor they walked in from. See more »


Commander William T. Riker: Data, we've only seen the Crystalline Entity once before. How do you know these metals will protect us?
Lt. Commander Data: I am not entirely certain they will, sir.
Commander William T. Riker: I was afraid you were going to say something like that.

The Entity's back and it gets its Captain Ahab
13 April 2017 | by Mr-FusionSee all my reviews

'Silicon Avatar' clearly defines the issue (the crystalline entity doesn't care if people are setting down roots; it needs to feed!). But while Picard wants to try and communicate with it (learning and all that), seemingly everyone else around him wants it destroyed; including a bitter scientist with a revenge thirst. The lynch mob has a good point because people are dying, but then again, the fractal menace reminds me of V'Ger and even the alien probe from "The Voyage Home", so it's not the most vile of creatures.

But this is a Moby Dick parallel, and it really comes down to the character of Dr. Kila Marr (Ellen Geer), and Geer does a good job spitting forth the hurt and seething hatred for this thing; and I think it's a nice way of readdressing the entity from episodes past and giving it some sort of closure.
