Minor nitpick here but in the demonstration scene, the history question about Napoleon to Alice skips one important detail: Napoleon was first exiled to Elba. He escaped but was captured again when he attempted to flee to the US. That's when he was exiled the second time to St. Helena. The scene makes it sound like he was only exiled once to St. Helena after being defeated at Waterloo, when that is not entirely correct.
You are partially correct, Napoleon did indeed get put into exile twice, although his first exile to Elba occured after his forced abdication in 1814 while the seventh coalition won the battle of waterloo in June of 1815, after which he was exiled to St. Helena. Thus the story is corrected that after his defeat at Waterloo his was indeed exiled to St. Helena, the story simply neglects to also mention that his exilement to St. Helena indeed was not his first exilement.
