Mikah was basically talking to himself (I was the audience who's participation was minimal) in the van tonight on the way home from the Doctor.
Mikah: You know that when you're really old you DIE. And then they stick you in the ground. When I die I will be in the ground until they dig me up. And use one of those bringing-people-back-to-life guns on me. I don't know. That might not be so good. Cause then I'll just be a zombie. But don't worry mom, I won't eat you. I'll try not to, OK.
