Factual error: A few days prior to Warrens' visit to the Hodgson's family, Janet watches the British comedy TV series "The Goodies" on TV. The episode that she was watching actually aired on December 22 of the year in the UK. Later, when Ed records the interview with Janet, it turns out that it's December the 21st. (00:28:20 - 00:31:25)
Other mistake: In the train scene, when Ed plays the two tapes separately, the first tape says," Help...It...Let...Go, Help...It...Let...Go." The second tape is then played, saying," Me...Won't...Me...Won't...Me." When played together, it should say," Help me, It won't let me go, Help won't, it me let go." Instead, it somehow turns into," Help me, it won't let me go, help me, it won't let me go." There aren't enough words in the second recording to fill or sequence the entire sentence(s). (01:45:00 - 01:49:00)
Factual error: All four Hodgson children go to Enfield Grammar School. Enfield Grammar School is a single sex boys' school, so the two girls could not go there. In addition, grammar schools in England are secondary schools. While the two girls (aged 11 and 14) are of secondary school age, their younger brothers are of primary school age.
Continuity mistake: In the beginning of the movie, students pour out from the school. Margaret and Johnny walk up to Janet and Billy by passing between two tall boys making them apart. In the next shot, the boys are walking side by side behind them. (00:09:50)
Answer: Valak was portrayed as a particularly powerful demon. In horror films demons are often portrayed as overconfident, and in this case it was thinking that Lorraine Warren would not be powerful enough to be able to defeat it. In addition, Valak revealed their name while Lorraine was in a dreamlike trance state, so it may have believed that she might not remember or make the connection at any point and be able to use it to her advantage.
