The Last Spiral, Part 1 - S1.E5

Another attempt to revive Jesus fails. Nanako and Dr. Ogami steal a plane, but Nanako, once again, believes she is going on vacation. The operation to begin the revival of the second Jesus is beginning, and she is on her way there. The government is about to find out Nanako's secret, and almost find out by going to what remains of the hospital. However, they are saved by a task force. The people who lived in the hospital are the ones who figures out that Nanako is a clone.

While in the air, a "hijacker" tries to stop them, but fails, mostly because the plane is attacked by fighter jets. In the process, an engine aboard the plane explodes after being hit from one of the jets, making flight almost impossible. So, Nanako is ordered to remove all that she can from within the plane. It fails, and she also, in vain, removes a few articles of her clothing to also help. Yet, Dr. Ogami and Nanako exit the plane, and at the very end, Nanako's bra falls off and into the air.
