I must do something, dads gone and mms knocked out!
"Suddenly Josef was the man of the family.."
The character is beginning to realize the seriousness of the situation while he and his family are held at gunpoint in their taxi. I think he will realize he cant be invisible anymore and must do something.
Isabel might realize that women can do amazing things too and I think this will motivate her and might give her strength later on.
Josef realizes he must take his father place and take charge and get something done in the situation.
