FRom about 5 min and 40 seconds till about 6 minutes into the episode, the voice actress for the female lead character, Sabine, changes the sound of her voice, whether intentionally or not, gaining a somewhat French accent. Interestingly enough this could be due to the fact that the voice actress in question, TIya Sicar, speaks a few languages, one of which is French.
THe whole episode just follows the trend for much of the second season to delve deeper into the pasts of the shows main characters , and its okay. The plot...she thickens :P
