Star Trek: The Alternative Factor

After a dimensional disruption shakes the known galaxy to its very core, the Enterprise is sent to investigate the planet of origin and find a man named Lazarus who claims ignorance. But Lazarus displays strange personality shifts from good to evil and it soon becomes clear that Kirk is not dealing with just one Lazarus... but two. And the second one is a psychopathic killer who means to destroy everything to eliminate his counterpart.

Recap

The Enterprise is on a routine patrol exploring a dead Class M world when suddenly the universe “blinks” around them, twice. Spock is at a loss to explain the experience but says it was as if the universe ceased to exist for a split second. They then detect a lifeform on the dead planet below and Kirk takes down a security team. They find a small alien ship and then spot a beard who rants about a Beast that is trying to kill him and destroy everyone. He falls down a cliff face and Kirk has him beamed up to the ship for treatment...

Episode Quotes
Kirk: What was that?
Spock: What my instruments read is totally unbelievable, Captain. Twice, for a split second each time, everything within range of our instruments seemed on the verge of winking out.
Kirk: I want facts, not poetry.

Lazarus: Why do you give credence to this man?
Spock: I fail to comprehend your indignation, sir. I've simply made the logical deduction that you are a liar.

McCoy: As we both know, I'm a bright young medic with a miraculous touch.

Kirk: Where is he?
McCoy: I don't know, Jim. This is a big ship. I'm just a country doctor.

Kirk: Sometimes pain can drive a man harder than pleasure.

Spock: Jim, madness has no purpose. Or reason. But it may have a goal.

Kirk: So you're the terrible thing, the murdering monster, the creature?
Lazarus: Yes, Captain. Or he is. It depends on your point of view, doesn't it?

Spock: And what of Lazarus?
Kirk: And what of Lazarus?



Episode Goofs
Robert Brown's false beard varies considerably in length and thickness throughout the episode.

Lt. Masters doesn't wear lieutenant braids, and is wearing a blue uniform despite the fact she works in Engineering.

Why does the "good" Lazarus have to sacrifice his life at all? All Kirk needs to do is beam up the bad Lazarus, destroy his ship, and lock him up somewhere so he never recreates it.



Analysis
What Changed in the Remastered Version
General improvements cited on the main series page. The planet receives a significant visual upgrade with landmarks visible from orbit and new orbital shots of the Enterprise are included. The phaser effect that destroys Lazarus' ship at the end is touched up.
