Not under those circumstances. The DN game should have taught you that much.
Sorry, but no. Indies have their own incentives, and you don't even know what Flower's is. Players are not assholes for treating them with uncertainty and doubt. That said, I trust Zemmi so far as I don't see any real reason for her to lie about this thing in particular. She has demonstrated lying, both explicitly and implicitly though, merely as a condition of existing as indi. She is *Cell*, after all.
