Question: Can't remember which episode, but when Celeste is put back into her body, she has a French accent and speaks French, but in previous episodes in the flashbacks she had a normal accent. Am I missing something?
House of the Rising Son - S1-E2
Continuity mistake: Near the end of the episode, as Klaus is watching Hayley sleeping, Hayley changes from sleeping on her side to sleeping upright in closeup.
Jackson Kenner: Klaus, if you want to fight me, come on.
Klaus Mikaelson: You mistake my intentions. I haven't come here to fight you. Not at all. This is to be an execution. Tell me, how exactly would you like to die?
Answer: She was in a different body.
