Gripen's condition stabilizes when she's near Kei, but nobody knows why. The two of them train for the upcoming test flight using the simulator.
If they can pass the test flight and Gripen can fight again, she'll be able to wipe out the Xi before long. But one day, Kei learns the truth about the Anima and the Daughters from an unexpected source.
The oscillation synchronizes, 
and it stabilizes.
.فإنّ التّذبذبات تتزامن وتصبح مستقرّة
Die Amplituden haben sich
angepasst und stabilisiert.
Las amplitudes de onda
se sincronizan y estabilizan.
La seccionalización
se sincroniza y estabiliza.
Les oscillations se synchronisent
et se stabilisent.
Le oscillazioni si sincronizzano e si stabilizza.
A oscilação sincroniza
e então se estabiliza.
…перестаёт скакать
и становится стабилен.
