I seriously doubt Lori had a kid out of some sort of an "arrangement". I mean Stevie is close to Jessie but she isn't that close. Ya know? I could see Stevie thinking it would fullfill something missing inside of her but realistically, I do not think it would. Just like Matthew wouldn't either. Anything is possible with these people though, so who really knows. As far as the whole kid thing goes, I think Stevie always wanted them. Her interviews over the years have always reflected that desire.
