Laura sits in the sickbay, shooting up her next injection, covered in blood. After a moment, with Hera onboard, the visions return. Hera, running through the Opera House. "What? Hera." She stands off, dropping her lab coat, barely able to walk, spaced out on drugs, and begins to walk toward the vision.
The squad comes around a corner, Helo holding both Hera and a gun now. The lights are flashing wildly. They pass an empty junction; a Doral comes around and fires into their group, dropping a Marine and hitting Helo. He falls to the deck as Kara takes the Doral out, and Athena falls on her knees beside him. It's bad, and bright, and red; he chokes the blood bubbles beneath her hand. Hera runs away, in the confusion, and Helo tells his wife to go after her. "No, you'll bleed out," she cries, twisted impossibly around; he pushes at her weakly, screaming, and she realizes it's what she would do, so she goes. And soon enough, she joins the vision.
Hera wanders through soundless war, past bodies and gunfire, climbing through the small places, past the sparks and gunfire, past Marines in position, past last defenses, as the lights flash. Laura heads past a Marine going the other way, barely standing. Cavil comes around with Centurions at his back, walking through gunfire, forcing the Marines to give up position after position, falling back before him. Laura's nearly stumbling; it's painful to walk. Suddenly, she spots Hera and they rush into each other's arms; she ducks behind another stack of crates with the girl and waits for Cavil's squad to pass. It's actually very suspenseful and scary, I'd forgotten. And when they're gone, she looks around, and Hera has disappeared once again.
Gaius and Caprica make their way through a hatch, and into one room, and then the next. He checks his gun, and he's all out. Caprica's got two rounds. And in the corner of the room, coincidentally: Hera, holding her hands over her ears. Laura and Athena meet at a junction, terrified as it comes true around them, and keep running in their separate nightmares. Caprica kneels to Hera as the women run down their stairs, and see her bending down. They are both so much more broken than in the vision. Caprica and Gaius make their way through another hatch, just as Athena and Laura converge outside, only to find it locked. Athena shouts her name, again and again.
Gaius was so beautiful, bloody and filthy, on Kobol, the first time he saw the Opera House. He stared around, twirled on a heel. They walk through the hatch now and his jaw drops, as the wonderful "Passacaglia" starts. "I've been here before," he says, and Caprica nods, staring around at the beauty all around them. Gaius blinks in the sudden light: they're supposed to...? Caprica smiles. "Go into the Opera House." She hands him the child, in the vision, and they head down the aisle toward the stage; on Galactica, she's got the gun as he cradles the child in his arms. Their baby, born in the brig.
