The aircraft was different on 3 different shots the opening had a G200 Gulfstream, the Ending Scene had a Gulfstream V and a G100.
In the closing scenes, the jet has a large "V" on the side above the windows, then the jet is seen to have a large "G" on the side at the end.
After reviewing the medical records of Christopher's deceased mother, Hotchner states that it is a textbook case of Munchausen by Proxy [newly named Factitious Disorder Imposed on Another (FDIA)]. Although FDIA does more often present itself in a parent/child relationship, it happens between any caregiver and dependent person (whether made dependent by the caregiver or a natural illness originally). It did not translate to Christopher. Even though Wilson Summers does strangle/choke then resuscitates his own son, it still wouldn't be a case of FDIA. In FDIA, the desired result is the attention and compassion given to the caregiver because of their dependent's health issues. Summers does his best to hide what he is doing to his son (e.g. moving the two from town to town frequently). He is denying himself the attention that someone suffering from FDIA would obsessively crave and seek.
The E.R. says that the layered bruising is evidence of Christopher being resuscitated multiple times via C.P.R., but C.P.R. breaks your ribs. If Christopher had really had C.P.R. performed on him multiple times, he would have multiple different rib fractures, all at different stages of healing.
At the beginning of the episode there are city shots stating it is Evanstown, WY; however, the shots are actually of the Old Port in Portland, ME.
