Who Killed Xavier on "The Afterparty"? 6 Theories

Oh, Zoe. She's caught between multiple people vying for her attention during the night — her ex Brett; the one she's interested in, Aniq; and Xavier. She keeps finding herself in Xavier's company, but in actuality, Zoe has no interest in Xavier and even says so at one point. We don't yet have the full story on what goes down between Xavier and Zoe while they're talking on the balcony, but seeing how scummy Xavier's been so far, we wouldn't be surprised if he said something completely vile and she flipped out and pushed him. It could be that it was an accident, but she's definitely a suspect in all this.
