Gregory Jones

Gregory is an 8 year old boy and member of the original group. Along with his father and mother, he  joined his aunt in the bunker to protect themselves. None of his parents was part of the scientist team, but both found a way to contribute to the group one way or another. Gregory made good friends with the other children, Matthew, Steven, Jerry and Brian and is often seen playing with them.
At first when the group is desperate, gregory is a beacon of hope as he says he is scared yet happy as he has his family and even his dog with him
After his parents' death, he was taken in by Karen and George and raised as their own. Despite not liking being with them, Gregory eventually came to acceot the fact that his parents were dead.
When Matthew's father becomes possessed, Gregory gets Matthew, saying that his father betrayed them, and so would he, making the two children fight. This event became a catalyst to pushing Matthew over the edge, leading him to betray the group.
Gregory was grounded for saying such mean things to Matthew, but he said he got angry at him because he hated Ryan because his parents died. George then explained Ryan was not the same man they knew, and that the aliens changed him. He also explained that Matthew only wanted to see his father again, and Gregory understood his mistake. He didn't manage to apologise to Matthew though, since Matthew obeyed his father and betrayed them as well. In the meeting where they decided what to do with the boy, George and Karen stood by Lydia's side and defended Matthew.
After Matthew betrayed them as well, Gregory blamed himself and thought that if he had stood by Matthew's side, he wouldn't have betrayed them. Brian disagreed though and said Matthew had to deal with the consequences of what he did
