Regarding the baby

I know everyone thinks the baby is Amber's husband at the time but I don't. When she went to Thayer's sister's house she said I haven't seen him for about a year. Nine months is a long time and you don't show up to someone pregnant asking about their brother and say "I haven't seen him for 9 months now." Also, the sister shows up to the hospital after she gives birth. She has not known her long enough for that to seem likely unless there was a connection between her and the baby. And the husband was not there. Just my thoughts! What do you think?
