Character mistake: In one of Lotus' phone flings conversation, she replies "I did hope you're be impressed."
Character mistake: One of Claudia's lines is "You're making it difficult maintaining a nihilistic pastiche." Not sure which fancy French word they were aiming for, but it does not appear to make sense in the context.
Character mistake: One of Bonnibel's lines is "I'm not one for labels, sugar, but I'm a bit old fashioned. Am I your beau, sweet heart?" Old fashioned or not, she gets her labels wrong; she'd be a "belle" (girlfriend), not a "beau" (boyfriend).
Character mistake: Francine's phone fling storyline says that she's a spy that asks the Player's help to send encrypted files disguised as photos, and they have to pretend to be lovers trading pleasantries and pictures next time she calls him. She says that she's going to turn off the jammer (which allows her momentarily to talk without being intercepted) "now" and says goodbye. When hours later she calls, she begins the conversation (and the act) with "Ready? Here we go." So she gives herself away.
Character mistake: In one of her lines reacting to the Yandere character, Nina says that she took the batteries out of the alarm in "the servant's wing." It's the servants' wing, plural (there's a literal army of maids there).
Character mistake: The second screen of Nutaku's "ending" begins with quotation marks that never close - and they were never supposed to be there in the first place, her line begins only a few words later.
Character mistake: One of Cassie's lines in the nude is "Take a picture, it's lasts longer."
Character mistake: During Babybelle's phone fling conversation about naming her flower-flavored wine, she says "Maybe I should say it tastes like a rose and it's thorns." Should be "its".
Character mistake: In the phone call from Nova, there is one branch of the conversation that starts with the protagonist asking "Shouldn't you have used this call to contact a lawyer or something?" But the protagonist IS a lawyer (amongst many other things).
Suggested correction: Even lawyers will almost always hire another lawyer to do criminal defense.
This correction doesn't make sense. Nova is not a lawyer, the player (whom Nova is calling) IS a lawyer. The player isn't saying something like "why are you calling a lawyer", or "shouldn't you have called a criminal defense lawyer." Nova called a lawyer and the lawyer's response was "why didn't you call a lawyer."
