Missing

Bellamy: If you are missing, he will send out a search party, himself included and will try calling your name, or looking for any signs of where you have been. He will get really worried and won't stop looking until he finds you.
Finn: He kind of goes a little crazy and will go out to look for you himself. He feels scared that you might be dead or worse.
Jasper: He will start drinking and losing himself. Jasper will feel guilty and will isolate himself from other people, even Monty.
Monty: He will get really sad and not be his usual hapoy self when around you. Monty won't be able to focus on his work and he thinks the worst.
Murphy: John will get angry, blaming himself for not being able to protect you and will seperate himself from others. If there is a hunting party looking for you, he goes and never stays behind. He doesn't rest until he finds you.
Lincoln: He looks for you and doesn't stop until you are found. Sometimes he will check at the camp to see if you ever came back and if not he will retrace to spots where you guys have been before.
Roan: He will feel guilty and won't stop trying to look for you. Roan will also send out some of his people to search for you.
