Shepard must convince A/K he's not a murderer and that Kai Leng is the true enemy, or he'll have to kill her. With A/K resolved, Shepard then has an epic battle with Kai Leng and Cerberus reinforcements over who gets the Prothean (still frozen a trance). The war outside intensifies, with windows, roofs, walls, etc. blowing out in bomb attacks, giving a spectacular view of Thessia under fire. Kai Leng wins the fight regardless, sending Shepard crashing down through a stain-glassed window. The last thing Shepard sees before he blacks out is Kai Leng leaving with his new Prothean prize.
