Corrected entry: When Blake and Rossi take out the safe, Blake opens it after Rossi suggests "2008, the year she [meaning Jennifer Jarreau] became a mom" but later when Jennifer and Cruz are in the March 2011 scene Jennifer tells Cruz she is pregnant. (00:12:45 - 00:23:30)
Corrected entry: When Blake goes to help Reid after he's been shot, she says "Ethan, Ethan, open your eyes."
Correction: Blake's overwrought because Reid pushed her out of the way of the bullet that hit him, so she calls him by her dead son's name - Ethan. At the end, when Blake accompanies Reid back to his apartment she says that seeing him like that touched a nerve, and Reid asks Blake who Ethan is, so she tells Reid all about her son Ethan who died when he was just nine years old, and also tells him that Ethan would have been a lot like him.
Corrected entry: The female agent is with Spencer Reid after he is shot and is saying to him to stay with her and starts calling his name, "Ethan, Ethan." His name is Spencer.
Correction: Yes, Alex does call Spencer by her dead son's name Ethan. This was done quite intentionally in the script. At the end of the episode, when Alex accompanies Spencer back to his apartment after he's released from the hospital, Spencer asks Alex who Ethan is, and she tells Spencer about her son, who died when he was nine, then tells Spencer that Ethan would have been a lot like Spencer. Rather poignant.
Correction: She was already a mom when this happened. The 2011 pregnancy would have made her son Henry a big brother.
