So we know that supernatural creatures like Daisy and Aqua are things in this universe. Does that mean that Odette is actually a vampire? How does that jive with her getting pregnant by the MC?
Dhampire babies confirmed.
Seriously though, I think Odette just put some kind of hallucinogen in her drink. Despite her appearance and her severe case of Resting Bitch Face Syndrome, she's more of a crazy party girl than a creepy goth chick. I don't remember all the dialogue from Eve's update, but I'm pretty sure it was stated at some point that Odette and Grace used to do some hardcore drugs in college. Seeing as to how Odette is friends with a dealer and has a rich-as-fuck business tycoon father, I think it's more than likely that she still has access to some of that shit. Hell, she could probably just call someone and ask if they could send her LSD if she felt like it.
You know, as I'm typing this, it just hit me that Odette might've roofied the MC. That's kinda fucked up. Like, I'm pretty sure that's a form of assault. Granted, the scene we got from it is some top-tier shit, but still.
