Kroykah! Or actually, don't Kroykah! Keep listening. It's time for a TrekRanks kal-if-fee as we take on the "Top 5 Vulcan Episodes" with our expert panel of host Jim Moorhouse and guests Thad Hait and Jarrah Hodge. Other than maybe Klingons, no species in Star Trek has had a bigger impact on the franchise than Vulcans. From Spock to, well, Spock again, the planet has received deep dives in culture, philosophies and language, and we tackle it all in breaking down a wide variety of logical choices.

Episode Rundown:

Diagnostic Cycle: Where we briefly get into the details of defining the show's specific topic and run through a roll call of previous "species" featured on TrekRanks.

Prime Directive: Each guest on this week's panel reveals exactly how they narrowed down list and made their final choices.

The Order of Things: All the picks are revealed with the TrekRanks' original "Five words and a hashtag" summary.

Secondary Systems: For a few extra picks that just missed our final list.

Regeneration Cycle: The panel recaps their picks and we dissect some of the interesting statistical anomalies that arose from the discussion (including exactly how many of the episodes pick actually took place on Vulcan).

Temporal Inversion: We flashback to a previous episode of TrekRanks and relay some of the feedback received from listeners, this time it is a great voicemail for the "Connective Trek" topic from episode 154.

If you have your own picks you would like to relay to us, please hail us at 609-512-LLAP (5527) and record your own personal TrekRanks log to let us know your Top 5 Vulcan Episodes. (Or you can record it yourself and just DM us @TrekRanks on Twitter.) Your comments could be used as part of a Temporal Inversion on an upcoming episode (and might get you a chance to be a guest on a future episode, too).
