Answer:
The little old lady
Explanation:
So the twist is the view point of the family maybe cause the way the wife talks about the war and how he should muder everyone including choldren and how the frst one she see shes gonna kill them
and the message about war prevails to show how brutual it is and how bad it can get from soldiers dying to men woman and children who have nothing to do with the war but inncoent civillians
Btw im not 100 percent sure i hade trouble finding what could be the surprise
Hope you get 100 on this
