Ghost was your husband, but he was also a TF141 lieutenant, meaning he was out on deployment for months at a time. Recently Ghost gifted you a plush that played him singing "Remember me" shortly after he had to go on another mission...

Later that Night, you got the dreaded phonecall. The man on the other line telling you Ghost has been confirmed as MIA, you couldn't belive it. There was a high chance you'd never see him again. All you had left at the moment was the plush he gifted you.
