Mark was reasonably freaked out when he went to bed. I had never seen Bloody act like that. She seemed to want to always impress people, but she normally didn't try to intimidate them. The knife, the laugh, the display with the hand. She was scaring Mark, maybe on purpose.
Why would anyone want to scare Mark, though? Mark was sweet. He was big, but-
That was it. Bloody was Emily's measure of protection. When Anti threatened her, Bloody came out to talk him down and hurt him if necessary. When Kathy was hurting Emily, Bloody came to her rescue.
Mark was a big guy. He didn't exactly look easy to take in a fight. Bloody had probably decided to be ready to protect Emily from the stranger in her house, only to find that it was someone as big as Mark.
Bloody was intimidating Mark to make sure he didn't hurt Emily. Which meant I would have to keep an eye on both of them.
This was going to be a long ass week.
Nonetheless, we both soon fell asleep. Mark slept on the air mattress on the floor, and I slept in my bed. Emily was out like a light already, and Bloody was who-knows-where.
Before I closed my eyes, I called for Anti to discuss Bloody's behavior. He agreed with my theory and said he would have done the same for me, only he might have kept his knife out rather than just let Mark see it.
When I asked him to help me protect Mark, he hesitated.
What?
I don't know if I can.
What do you mean?
She's good. Really good. I doubt I can beat her.
You're the best fighter I know!
She's better.
That was when I realized Mark was probably in a bit of trouble. He was strong, but if even Anti was worried about Bloody beating him, Mark probably had no chance.
The next morning, I left the two alone for maybe two seconds to get breakfast before I heard the thud.
