Dylan’s door was most likely locked. I’d certainly keep my door locked if my bedroom were right next to a kitchen with an unlocked slider (or one so easy to break into that police found no evidence of forced entry).
Xana worked at the same Greek restaurant as Maddie, so BK could have been targeting both women. He might have planned to make his way to Xana’s room after taking care of Maddie and Kaylee (I still think he knew she’d be there because of her Instagram posts and Saturday being game night—he didn’t need to recognize her car).
I also thinks it’s plausible that he planned to kill Ethan, too. BK did not like men, either, IMO, at least not the ones who out-competed him with women (the Chads in Incel-speak). BK’s an observer. He knew Ethan would likely be incapacitated that night due to alcohol.
Think about BK’s second encounter with the curly-haired pool party guy, Basseth Salamjohn (interviewed by Dateline—not the DJ, the other one).
According to Airmail (via
Inside Edition, Salamjohn says BK abruptly stood up, collected the digits of two bikini-clad women, then walked off. Luckily for the women, they never heard from him again.
BK was just showing off to Salamjohn. Showing his superiority.
