I was thinking some more about somebody yelling around 4:00 a.m., "Somebody's here".
What are the circumstances where you would yell into a house with possibly sleeping roommates at night, that somebody's here? If you thought somebody was there, you would probably assume it was a guest of one of your roommates coming over late night. If you saw the back door open you would think dang, my roommates were born in a barn or something.
Or if went into the kitchen and you saw the back door open and you thought it was a little bit suspicious, you wouldn't just yell, somebody's here. You might look around a little bit to see what's going on first, before yelling out. You would look into the living room and the kitchen, maybe poke your head down the hallway, look at the staircases a little bit. You might text your roommates to ask if anybody came over.
So this is my theory on what I think happened.
I think xana was sitting there in the kitchen or the living room after 4:00 a.m. scrolling tick tock and eating her food.
And Bryan opened the back door and walked right past her and went upstairs.
And she may be caught a glimpse of him as he went upstairs. And that's why she yelled, somebody's here.
Bryan went upstairs and got right to work. The murders upstairs probably took him like a minute. Then xana heard the noises upstairs. Xana went upstairs to look. And then she came running back down.
I think that's how bold Bryan was.
I'm wondering if he set up a phone and internet jammer before he went in. That would give him more confidence.
Edit- I looked at the house plan again and I see if xana is sitting on the couches in the living room, she cannot really see into the kitchen because the couches are on the far right wall. Facing towards the front of the house. But maybe she heard the back door open.
I'm replying to myself here because I've been thinking some more about this situation of somebody yelling, somebody's here. I think I have some more new thoughts on it.
I think xana was sitting in the living room couch when Bryan came in through the backsliders. She was eating her food and looking through tiktok. The couches face away from the kitchen and are behind a wall from the kitchen, so she would not have a direct view to the kitchen.
But she probably heard him come in through the sliders, and yelled "Somebody's here." Now remember DM peeked out her room after she heard that, and she didn't see anybody. So that means that xana was not in the kitchen. And it means that Bryan had already gone upstairs.
Then dm said she heard somebody walking up the stairs. And then after, she heard somebody running downstairs. Notice it was only one person she heard, because the person must have gone upstairs and then downstairs. It couldn't be xana because then dm would have heard Brian too. She would have heard that two times. So it was probably just Brian.
So I believe the person she heard go upstairs and then downstairs, was Brian, before and after the murders upstairs. Not xana. Also because xana would probably be screaming if she ran down being chased by Brian.
I think after the murders upstairs Brian ran down the steps and then he ran down the hallway, right past xana, to Ethan's and xanas room. Opened the door went in and right away stabbed Ethan in bed.
Xana saw Brian right run past her in the living room. She didn't know what was up, if it was a prank or what, so she went over to her room to look. When she walked in she saw Ethan stabbed and Brian was there maybe at the side wall and then stepped behind her. That's when she whimpered because it was a shocked scared reaction. And Brian said I'm here to help. And that's when the fighting starts. I believe xana grabbed whatever was around to try and fight Brian off, and in my opinion it could have been a golf club, since Ethan was a golfer.
So no I do not believe the date line interpretation. Of course the police would have more evidence, like if there was blood evidence of stabbing upstairs of xana etc. but short of other evidence I believe this is what happened.
Edit- although the food was found in the kitchen afterwards. Hmm. So that would not work with my theory exactly of xana always being in the living room. So I'll have to modify the theory a little bit and here's the modification. After xana heard somebody come in through the kitchen sliders, she yelled somebody's here. Dm looked out did not see anybody. And then shortly after that, xana got up and went to the kitchen and put her food near the sink. She saw the sliders open. And that's when she heard the noises upstairs. Then Brian must have run down the hallway and she could see him running past the opening in the kitchen. And then she went to her bedroom to look.
Edit - I believe Brian wanted to kill both xana and Maddie because he feels they blew him off and disrespected him in the vegetarian restaurant. But I think his primary focus was Kaylee. Because after following xana and Maddie, he started getting into Kaylee as well. And he came there that night, because he knew from social media it was her last night there. I think Brian would have tried to go and kill more people but xana tuckered him out from that fight they had. And he knew he was there too long already so he just left. I'm sure xana was the first one who really gave him a good run for his money. I'm sure Brian has killed before and he was always successful in just stabbing people unexpectedly. But this time xana probably put Brian in fear of his own life for a second there, after he got some good blows to his stomach and chest and maybe his head with a golf club. So that's why he decided it was better to just get out of there.
