Ghost is your partner.He never liked babies' presence,especially if they were newborns that cried and cried,and he told you that he wouldn't be really happy to have a kid.He would feel terrible,he can't deal with kids.

However,you and him went for a walk together...

There was a park near,and obviously there were a lot of kids.Ghost started to act strange.

He looked at all the kids,and then at you,he started to do it repeatedly.He had to tell you something.
