Season 4, Episode 4:
In the wake of Cally's death, Galen is holding a prayer service for her which is attended by most of the command crew.
Afterwards, Tigh and Tory confront Tyrol and discuss his wife's death. Tory asks the chief if Cally killed herself because of him, and Tyrol questions his memories and his wife's misplaced thought that they were having an affair. Tigh assures Tyrol that his feelings towards Cally were real, and it had nothing to do with being a Cylon.
Tigh then visits the brig to see Caprica-Six, and tells her that her request to see Hera has been denied. Caprica-Six thinks there's another reason he keeps visiting her, and it is revealed to the audience that Tigh sees Ellen's face whenever he looks at her.
Tory in turn visits the commune to see Baltar, and seduces him while they discuss the concepts of pain and pleasure. The mood is ruined when a fundamentalist group, the Sons of Ares, attacks the commune. Baltar hides behind a pillar as they attack the cultists and trash the commune before leaving a short while later. Baltar discovers the identity of his attackers when he sees graffiti they've painted on the walls, and HeadSix tells him that the gods are fighting back.
Baltar tells the cultists that they have been targeted for what they believe in, and calls on them to renounce the gods. He then heads to a temple and disrupts a prayer service, which eventually results in the temple being vandalized by the cultists, while Baltar is taken away by Marines in response.
In the hangar bay, Tyrol has finished completing repairs for Racetrack's Raptor, but mistakenly forgets to replace a critical fuse. When the Raptor goes out on patrol, the thrusters fail and the ship crashes into the portside landing deck.
Afterwards, he is confronted by Racetrack and Skulls and admits that it was his fault for not being focused during the repairs. He eventually becomes fed up with the situation and walks off the job.
Bill visits Roslin in sickbay as she undergoes another round of cancer treatment. Her hair has fallen out, and she is wearing a wig. After Bill reads her another passage from one of his favorite books, she tells him that Baltar has been placed in the brig once again. They both agree that they can't have a religious battle happening on Galactica, but Roslin has an idea to resolve the situation. She goes to Baltar in the brig and reveals that she has cancer and is near-death, and that she doesn't have the patience or drive to listen to his ramblings anymore. She urges him to stop his crusade, and frees him from the brig.
Tigh once again goes to visit Caprica-Six after seeing her earlier in the day. When questioned why he keeps visiting, the Colonel tells her that he wants to know how it feels to have so much human blood on her hands, under threat of being executed by Marines. When she tells him that she is still finding a way to deal with the pain, he orders the Marines to leave and stays behind to watch her.
Bill goes to Tyrol, who is drinking in Joe's Bar, and asks him why he left. Tyrol goes off on a rant about Cally's character flaws, and reveals that he still has feelings for Sharon. Despite his best attempts, Bill sees that Tyrol is unwilling to listen to him, and subsequently demotes him because he is a danger to others.
A Quorum meeting is convened aboard Colonial One. Lee argues with Roslin over Baltar's commune, and suggests that she's too concerned with her focus on him. When she tries to counter, he argues that they can override her position because a resolution she passed barring the size of his group cannot stand.
Baltar makes his way to the commune, but is stopped by a Marine who tells him of Roslin's resolution, and is repeatedly beaten back by the Marine to the point of spitting blood. HeadSix urges him to continue, and he repeatedly tries to enter the Marine while being beaten. Eventually, Lee arrives and orders the Marine to leave, then tells Baltar that the provision has been rescinded. Baltar thanks him, saying that his God compelled him to do it.
Caprica-Six wakes up in the brig to find Tigh watching her, and they have a conversation about learning from pain. He eventually turns off the surveillance cameras for her cell and enters, and she tells him that she can give him clarity. When he refuses, she beats him and asks if he understands the clarity that comes from pain. She continues punching him, as he envisions that Ellen is the one hitting him. Eventually, she realizes that beating him is not what she needs, and they begin to kiss...
Later, in sickbay, Bill is finishing his book while Roslin has her treatment. They talk about Lee, and she admits that he was right in rescinding her provision and supporting Baltar, but that his actions could have dangerous consequences. He finishes reading the book to her as she falls asleep.
Baltar delivers a speech to his commune imploring them to love others once they love themselves. Lee watches and sees Tory smiling, then leaves the commune
