Yeah, I don't get how people are not seeing it this way. We may be missing Laura's perspective, but it's not like the story hasn't given us some massive hints.
For example,
when Harry proposes to her, Harry's inner dialogue tells us that, at least for a moment, he sees genuine happiness in her eyes before she makes herself go blank.
She was
happy. And this was after spending all night fucking Luca
without a condom.
She was happy about it in the normal route, too. The difference is that she said yes in the Normal route, but she is saying no now. Why is she saying no now? Because if she said yes in front of all those people, it would eventually get back to Luca and her plan would be ruined.
There is actually no doubt in my mind that Laura hasn't fallen. Not at this point, at least. But, if it turns out that she has, I just don't think I would be able to understand her character anymore.
Oh god... If I don't understand her...does that mean she's going to cuck me next?
