Just played through this sequence and absolutely loved it. I know Natasha is on the side character/completion route (and I'm excited to see new girls introduced), but I'm happy to see her still getting interesting events.
That's nice, to my mind Natasha has generally been able to do a fair effort (circumstances given), and it looks like she will keep doing so the last stretch over the goal line too.
As for completion path that is absolutely correct, she is indeed that, and content towards her should be seen as moving her to completed, something which (based on at least my take on the yacht preview) looks like it could become more general for girls in the future.
