The last paragraphs of the unsent letter that Nina found in Sophias apartment, which can be seen when she closes the notebook, don't match Nina's voice-over.
Bank CEO: People say I'm sending Sebastian and Nina to New york so neither will take my job. Hey, perhaps that's partly true. You know, like these butterflies that surround us this evening, it's a time of transformation, new beginnings.
Nina: So many years without you... this is my penance. If you will come back to me, I will never leave you. Never again. And we will be sisters for ten thousand years.
