Jones what is the meaning?

Maybe Jones is being saved for the future by the alien. One thing is the locker is not latched and seems to be just in the closed position. I don't know about that scene it might just be mistakes by the writers. Somewhere in the story the alien is supposed to break into some food storage containers and eat to start growing big. The cat seems to have found the shedded skin from when the creature was more a youth, and it seems hard for the aline to be able to catch such a small animal. I think the locker scene is a crutch to separate Brett from the team.
