SPOILER POTENTIAL!Possible MEDIUM spoiler:
The vet diagnosis without blood work, etc.
After so many years in a totally drugged state how did the manager make the connection? Way too far fetched for us.
No mention of the keys to the store or how the doors were locked again AND the alarm reset.
Maybe she could get away with a fake birth certificate but how on earth could she tell the woman the baby died, there must have been other people in the room with the doctor, at least one nurse.
That is all I can think of for the moment.
The following road is fraught with startling leaps to conclusions and wild fancies of rationalization:
To the first question, I fold. Can't imagine they did that for any reason other than to expedite the plot. That aside, I loved the way they handled the parental anxiety over telling the daughter...and it was terrific when she told them she already knew (she's gifted, too) and didn't say anything to her father because she knew he'd be upset...because he loved the dog.
I don't think any case was made for her being out of her mind at the time of giving birth. She need not have been so burned out she'd never remember giving birth or hearing the baby died or recalling the doctor's name. She could easily have entered rehab in the intervening 15 years. Perhaps she had huge regrets about her child. She surely must have had a certificate of death for him, signed by the doctor. Since they never explained how she knew the boy was her son, she must have 1) recognized the name and 2) asked him about his parents. I think things added up for her...but the exposition just wasn't there for the viewer.
You're right about the keys/alarm. My fervid imagination took over and presumed she used her son's key. If the manager had been there, the alarm might have been deactivated when the doctor entered. I don't recall if an alarm went off after Allison smashed the window to get in, but there could be a totally different alarm system to alert police when something violent happens. (Or is that too much of a rationalization?
)
I wasn't real clear on the birth part, either. I cannot imagine how she could have gotten away with it with other people there... unless she were in some poor clinic at the time and took the baby out, telling others she was getting it to a proper hospital for treatment. But...I can only stretch so far...
As I said...I was tired. I did enjoy the episode.
