On the wall behind Lee and Admiral Adama during Lee's farewell is a plaque containing rank patches for some US Air Force enlisted and ROTC ranks.
As Lee receives his official farewell, he shakes hands with all major characters from the Galactica, except Colonel Tigh. This is a subtle acknowledgment to their respective grudges dating back to Lee's mutiny in "Kobol's Last Gleaming, Part 2."
The model numbers of all seven human-form Cylons (not including the Final Five) are revealed in this episode:
No. 1 - Cavil
No. 2 - Leoben Conoy
No. 3 - D'Anna Biers
No. 4 - Simon
No. 5 - Aaron Doral
No. 6 - Number Six
No. 7 - ???
No. 8 - Sharon Valerii
Roslin: You are so buckled up inside. You can't take any more loss. Your son's leaving, this, me. I know it.
Adama: (drunk) No one's going anywhere.
Roslin: Okay, here's the truth. This is what's going on. You want to believe Kara. You would rather be wrong about her and face your own demise than risk losing her again.
Kara: I'm no more a Cylon than you are, and you know it.
Roslin: I wish I did.
Kara: I've put my life on the line for this frakking ship. I have ate, slept and fought next to the people that I love. I have pissed off my friends. I have broken more rules than I followed. I frakked up, OK? I messed up. (pause) But it's all that I have. Those people are my family. And none of us belong here.
The Hybrid: The excited state decays by vibrational relaxation into the first excited singlet state. Yes, yes, and merrily we go. Reduce atmospheric nitrogen by 0.03%. It is not much consolation that society will pick up the bits, leaving us at eight modern where punishment, rather than interdiction, is paramount. Please, cut the fuse. They will not harm their own. End of line. Limiting diffusions to two dimensions increases the number of evolutionary jumps within the species. Rise and measure the Temple of the Five. Transformation is the goal. They will not harm their own.
Natalie: (to Boomer) Have you lost your mind? Our identities are determined by our models. Each model is unique. We belong together. (to Cavil) You know this better than anyone. Mechanized copies? Those are your very words.
Cavil: Something has changed. Those are your very words, and I wholeheartedly agree.
Cavil: We're mechanized copies! There's a reason the original programmers clearly felt that it's a mistake for us to contact the Final Five.
Cavil: Violating that programming threatens our survival.
(Kara holds President Roslin at gunpoint)
Kara: I want to hate you so much. So much. You had a vision, remember? The arrow, the temple? I went down to that planet with you, and it was a frakking toaster party. A lot of good people died, remember?
Roslin: Yes, I do.
Kara: I trusted you. On a vision. That's it. A vision! I saw Earth. I saw it with my own eyes, and it's calling me back. We're going the wrong way. Why can't you trust me?
Michael Angeli was nominated for a 2008 Emmy Award in the category of "Outstanding Writing For A Drama Series" for this episode.
For the initial UK broadcast of Season 4 on Sky One (April 15, 2008), this episode aired back-to-back with the previous episode, "He That Believeth in Me." The final credits of both episodes were shown simultaneously, side by side, in split screen at the end of the broadcast.
The numbers of three Cylon models were revealed for the first time in this episode. The Cavils are number 1, the Leobens are number 2, and the Simons are number 4. We now know the numbers of all of the "Significant Seven" Cylons.
As of the opening credits, there are 39,676 survivors in the fleet, 22 fewer than listed in the previous episode.
James Callis read the "Previously on Battlestar Galactica" line at the beginning of this episode.
The episode title reflects the traditional idiom, "Six of one, half a dozen of the other." The phrase is used to point out that two differently named items or collections are really the same thing.
"Six of One" is also the name of the "Official Appreciation Society" for the cult favorite TV show The Prisoner (1967). Patrick McGoohan's character "No. 6" inspired the naming of the Battlestar Galactica character Number Six (played by Tricia Helfer).
