Spoiler policy: If you want to discuss a plot point from an upcoming episode, something you know is going to happen because it’s been revealed in interviews or some other canon source, put it in a spoiler box, and label the box so we can decide for ourselves whether or not it’s something we want to know (example here). If it has already been aired, or if you’re simply speculating about what might happen in an upcoming episode, there’s no need for a spoiler box.
Regarding episode numbering, see comment here. Note also that in the link to the preview below, and on the official scifi/battlestar site, this is officially episode 415, despite what’s found on other sites.
This week’s episode title: “The Oath.” Written by Mark Verheiden, directed by John Dahl (yes, that John Dahl).
Preview for the episode (holy frak).
One-minute promotional excerpt (not very spoilery; just enlarges on one element of the major plot thread covered in the preview; but suggests very bad things are afoot).
Links to previous threads, for anyone who wants to review:
4.8 - “Faith” (in which Starbuck’s crew finds the wounded basestar, and Roslin deteriorates in Galactica’s sickbay)
4.9 - “Guess What’s Coming to Dinner” (in which Starbuck’s crew returns with the basestar; Gaeta sings about his missing leg; the Cylons propose destroying the Resurrection Hub, and then immediately begin scheming to betray humanity while the humans do the same; Athena murders the Six Natalie; and Roslin gets “kidnapped” when the hybrid panics and jumps)
4.10 - “Sine Qua Non” (in which the disappearance of Roslin prompts a search for a replacement President, and erratic behavior from Adama; Cottle reveals that Tigh has impregnated Caprica Six during his “interrogations”; Lee is chosen and sworn in as interim President; Adama relinquishes command to search for Roslin; and the character of Romo Lampkin is made considerably less interesting)
4.11 - “The Hub” (in which Roslin’s isolated basestar crew, human and Cylon together, cooperate to destroy the Hub without the help of the fleet)
4.12 - “Revelations” (in which a mutually-assured-destruction standoff is resolved when Lee abruptly finds a compromise to achieve a tentative peace, and human and Cylon gaily traipse off to the now-known location of Earth, only to find it was turned into a radioactive cinder long ago)
4.13 - “Sometimes a Great Notion” (in which the discovery of the ruined Earth has serious repercussions for the fleet, and various people melt down and give up: Roslin burns her scriptures, Adama begs Tigh to kill him, and Dee shoots herself, among others; the Penultimate Four experience flashbacks while on Earth, and realize that they lived there two millennia ago; Starbuck finds her own corpse in the wreckage of her viper, and Leoben wigs out; and Ellen Tigh is revealed as the Final Cylon)
4.14 - “A Disquiet Follows My Soul” (in which Adama presses the fleet to tolerate the Cylons and adopt their technology, causing resentment to grow in the fleet, including among Colonial officers, chiefly Gaeta, who begins plotting resistance efforts with Zarek, while Baltar stokes negativity of his own; Tyrol discovers he’s not the father of his child; and Roslin finally joins Adama in his bunk)
One comment: In the last episode, Tyrol, representing the Cylons, asked the Colonials to consider granting full citizenship to the Cylons, with everything that entails: a seat at the council, protection from Colonial military, the whole nine yahrons. Half the room was appalled at the prospect of essentially forgiving the Cylons for their holocaust and welcoming them into the fold; the other half was shocked that the Cylons would trust the Colonials to honor such a commitment. Yes, said Tyrol on the second point, I convinced them that Adama can be trusted, and that he takes his oath very seriously.
Now we have an episode titled “The Oath.” Coincidence? Or introduction of a thematic path?
