Stargate Universe Episode 1.19 Incursion (Part 1)

With the whole crew questioning his decision, Young refuses to restore the atmosphere in Telford's quarters. Scott attempts to stop the murder, but Greer holds him back, and fear in the control room keeps Brody in Young's thrall. But the moment Telford loses consciousness, Young orders the life support restored, and rushes in to revive Telford. As soon as he does, Telford snaps back from his brainwashing, and tells Young that the Lucian Alliance has the technology to dial Destiny, and is on its way to take the ship by force. Young prepares the whole crew to defend the ship and route the intruders by venting the gate room upon their arrival. Telford, while relieved to be of help, is plagued with feelings of guilt, and doubt is sown among the crew as to the reliability of his intel.

At the Lucian base, Rush was temporarily unconscious due to his connection with Telford, but once revived, continues his forced labor. Earth-based forces prepare to retrieve Rush, but are blocked by Lucian technology and nearly destroyed. Kiva, in response to the attack, orders her team to dial Destiny, even though the incomplete engineering will cause their base to explode once they do so. The Lucian Alliance pile through into the gate room at lightning speed and take Rush with them, severing the connection between him and Telford. With Rush and Telford's lives at stake, Young cannot vent the room as planned, and so the Lucians establish themselves onboard.

Young demands that they surrender, but Commander Kiva has other plans: Lucian technology is able to open the doors to the gate room, and the attack is on. After an intense firefight, the Lucians fall back to the gateroom with several hostages. Camille attempts to negotiate, but it is soon clear that she has no bargaining weight, and the Destiny team is sharply divided.

Eli and Chloe, who have been analyzing the scene, decide to retreat to higher ground, but Chloe is shot in the leg and they're forced to take cover in a faulty elevator. Eli bandages the wound, and the two attempt to find someplace safe to hole up. Chloe continues to lose blood, however, and though Eli attempts to keep her spirits high, the pair's hopes falter.

Kiva, meanwhile, wants to push her agenda by shooting some of the hostages - including Riley and TJ - but Telford, now pretending to be a mole, convinces her that that will only force Young's hand. He gathers a special force team and makes a secret signal that Young should attack, but as they prepare to breach the border, a Lucian private is mysteriously reduced to ash - an event that causes all of the ship's systems to falter. Young vows to Kiva that it wasn't his doing, but tensions are ratcheted up by the event.

And Rush is piqued: Destiny dropped out of FTL because of the active gate, but there's no clear reason why it hasn't gone back to FTL.

Their one advantage could come from an unexpected source: Kiva wants TJ to save one of her wounded officers, and as they don't have the necessary medical supplies, they may be willing to negotiate for his life. But Young has a different idea: Use their need as a window to take them out.
