alright i'm just going to try to sum up what little logic there is here:
1) there is ~$16k sex doll Peter has, somewhere
2) there is also a real, living human being that might be named Ashleigh
2a) these two entities are interchangeable to Peter
2b) these two entities are also interchangeable to the real girl (meaning she is fine pretending to physically look like the sex doll)
3) there is a living baby
3a) Peter has at least had temporary possession of this baby
3b) either real girl or sex doll also has had possession of this baby
what we don't know:
1) why Peter would go through this ruse
1a) where he got the funds for the sex doll
2) why this real girl would go through this ruse
2a) what her relationship is with peter
2b) what her parents know
3) whose baby this is and where it came from
my inferences:
1) real girl had a baby
1a) the skinny photos were of the sex doll
1b) the hospital photos were of her
OR
•1) real girl faked pregnancy
1a) the skinny photos were still of the doll
1b) the hospital photos were still of her
•1c) still no idea where baby came from
2) real girl's parents think peter and real girl are in a relationship
2a) they have no idea about the elaborate sex doll ruse
