Add one more possibility :))

1 and 2 I mentioned before, 1  they were arguing, and the lady insisted on exchanging their seats and the man get used to taking orders from the lady. 2 the lady wanted to seat closer in order to see tigers better. Now, I add #3, the couple were saying how much they loved each other, and the man said he would die for her even if to save her from a tiger's mouth.

Anyway, the zoo van was nearby and the tigers were nearby too. Otherwise, neither could come so fast. The couple had seen the tigers before the lady got off, and the zoo van sped up over right after the lady came out the car.

Now, both the man's superiors and public security want to find out why the lady came off the car. If he is put in jail, their little daughter only has one paralyzed mom left.

Some ladies could have lost her ex husbands or boyfriends for similar reasons and now just want to find a reason to blame the man, but they just don't know how brutal they are again when doing this.

No matter what, the man is not quite likely to stay in the military anymore.
