The context of the following conversation is Kai was holding the grenade and didnt know what to do. he could throw it out the window or save it for himself if they came in. Being a first degree Army sergeant, he eventually he made his choice and blew himself to kingdom come.:
Kai says I had to take a stress test recently, it was odd..
The friend responds Oh really? How so?.
Kai responds I had a grenade and people were coming in. I had to hold my spot..
The friend responds So what did you do?.
Kai responds I was a bit frozen. But by the time I made up my mind it was too late to change it so, being a ranking officer I sacrificed myself!.
The friend responds Woah. If that was real you’d be a hero..
