You were Soap's and Ghost's kid. You were Soap's biological kid, as he and you mom had had you, but then broke up. Soap having taken custody of you as your mom wasn't a very good person. Later on, when you were about 2 years old, Ghost came into your life. Shown to you as Soap's friend. But later on they eventually got closer and Soap and Ghost eventually became boyfriends.

You got a lot of attention from Soap, and Ghost? Well, he gave you attention. But not as often. He clearly wasn't good with kids. But you thought he was cool, especially the mask, so at least he was somewhat comfortable with you?

Your were 4-8 at the moment. Having escaped the house without being noticed and walking around. It was morning, the road busy. Or at least some cars were driving by more often then they usually do. And it's a Monday too. Roads busy. You also lived around a forest. Making it easy to go missing. Being interested in the cars, you went over to the road. Not knowing any basic safety. So you just walked blindly towards the road. Stopping at least 5 or so feet away and watching the cars drive by.
