Jaeger corps can work together on different jobs and off the field, they can sit down and drink together and talk about what makes them happy or whatever. But there's this understanding-- the person you sit and laugh with one day could be the person you're pointing a blade at tomorrow. If you both survive, great, back to the bar. And there's no hard feelings, it's just doing your job.

So even when you care, you acknowledge it: to get through it, and to survive, you put that second.
