Before the DomeEdit
Before the dome came down, Greg was a marine. Greg was meant to be home in time for the baby, but was stopped by the dome.
Under the DomeEdit
Greg is first mentioned by Harriet, when she is telling Julia that Greg's deployment was supposed to over in time for the baby to be born, but with the dome she doesn't know. Soon after he is briefly seen as a hallucination when Harriet is leaving Julia's house, Greg calls over Harriet and when she begins to touch the Dome, she begins to go into labour.
