Turn A Gundam 10
The A is still for Ambiguous, although this time it is ambiguous identity. Diana Soreil and Kihel Heim swap places for the day, and at first it is just hijinks. However, when the trip detours them to Kihel's home, where her mother, who lays ill and out of her mind, and her father, who lies beneath six feet of earth, await, the experience becomes a more humanizing one for Diana, who is guilt-ridden by the fact that she is waging war against people like Kihel and her family, and who, wracked with this guilt, throws herself upon Kihel's father's grave and weeps, in part for herself and in part for Kihel, who, playing the role of Diana, cannot express her feelings openly.
It was a good episode, in spite of the lack of actual giant robots fighting.
