Sam:in the book he is an angry teenager who, because of his leadership abilities, unwillingly ends up as mayor when the adults disappear. Oh, and he can also shoot light from his hands. Once the adults are back and he grows up a bit, he would make a good
entrepreneur, putting that leadership to good use with something he actually wants to be in charge of. Alternatively, if he wants a mindless job (I wouldn't blame him after all he's been through), he could use his power to generate clean electricity and lights
that don't use energy. I'd let him do surfing on the side.
Astrid: She's so smart she could be anything she wanted to, but she'd make a good biologist after studying the mutations.
Cain: Prisoner. Definately, This boy should be locked up.
Little Pete: If he could communicate with the outside world, he could put his great imagination to work as an engineer.
Quinn: Continue his fishing career.
Edilio: He doesn't like when kids have guns, but he would do well in the military when he's older.
Orc: Heavy work seems to do him good. He could do evacuation work, digging people out of the rubble. He would like to see the direct impact he has on helping people.
Drake: Mental institution inmate. This series has some sick kids.
Diana: I think she can reform. But What to do with her then? Surprisingly, I think she would make a good social worker.
Lana: She can heal people, and she's brave. But she doesn't like using her power. If she doesn't want to go into medicine, she could maybe go into troubled areas as a reporter or aid worker.
Albert: He actually likes leading and he did a great job with McDonald's. If he cleans up his act, he could start his own restaurant. To take advantage of his "creative" nature with limited supplies, he could go with Lana and help supply food.
Bonus: Hunger Games!
Katniss: Stubborn, smart, good at survival. Let's see... a contestant on survivor would be too easy, but she could teach other people survival and their families, or, better yet, team up with Gale to supply wild food to stores or restaurants or something.
