Character mistake: At the end of the episode, Abby Carmichael says that professor Rousseau will be convicted of three class-A felonies, with a term of a year each. According to NY state laws, three class-A felonies would lead to the death penalty; Abby meant to say three class-A misdemeanors.
Character mistake: Olivia's talking to Cassidy about the previous night. She says, "We went to Meloni's place." I assume she meant Stabler.
Suggested correction: She didn't say place. She said "we went to Maloney's, we got drunk." Maloney's is a name of a few bars in New York.
