Episode 24: Endless Poem

Setsuna contemplates his memories of Lockon, who vouched for him when he first became a Meister. Tieria blames Setsuna for Lockon's death, but Sumeragi reminds him that their true enemies are still nearby. Meanwhile, having lost over half their GN-X and the Throne Zwei, Sergei suggests the UN force withdraw. However, UN headquarters reveals that reinforcements are coming and orders a second attack. Back on Ptolemaios, the Gundams undergo repairs and upgrades. Tieria suggesting they destroy all the pseudo-GN Drives so that they can resume their original plan. The rest of the crew contemplate their pasts, but an alarm signals that the UN forces have arrived. Alejandro Corner joins the UN forces in a large, golden Mobile Armor and fires a massive particle cannon at the Ptolemaios, which barely evades the blast. With Kyrios and Nadleeh protecting the ship, Setsuna and Lasse attack Alejandro but can't penetrate his GN Shield. Alejandro continues to fire on Ptolemaios causing massive damage. Tieria activates his Trans-Am system and destroys several GN-X, including Patrick Colasour's GN-X, but suffers extensive damage. A GN-X manages to approach Ptolemaios and fires directly into the bridge resulting in the death of Christina and Lichtendahl. Sumeragi, Ian and Feldt manage to escape in one of Ptolemios' containers. Lasse rams Exia's container into Alejandro's shield and breaks through. Exia and the GN Arms escape the destroyed container and charge back at Alejandro.
