Aaron highlights one of our favourite episodes from the Alternate Realities Star Trek set…

This is no surprise either, as this time-warping, alternate-reality creating episode is one cracking bit of sci-fi.

The episode opens with Guinan conversing with Worf about possible mates for the Klingon warrior on the ship.

Gone are the families and children, replaced by phaser-toting security, military shipwide announcements and… Tasha Yar.

She simply knows that this isnt right.

It soon becomes apparent that the Enterprise-Cs appearance is the cause of the alternate reality.

The rescue mission was halted by a Romulan attack, and both the Enterprise-C and the outpost were destroyed.

Garrett and her crew agree to this request, and reality returns to normal.

She reveals that she died an empty death in the real timeline.

At the very least, she wants a good death a death that means something.

Some points in the episode arent quite as strong, however.

The prime example being the Sonic Screwdriver that is Guinans never explained intuition.

If this is a warship, then why is there even a bartender onboard?

Still, despite this arguable issue,Yesterdays Enterpriseis an excellentTNGouting.

Not only do we see a great alternate reality and the Enterprise-D destroyed (again!
