The day came for the feast and it was as joyful as it could be.

"Well seeing as we learned everyone's favorite appetizers I decided to prepare a bit," Zedaph began, "and if you are afraid I poisoned them or something I'll take a bite."
"How did you get access to the kitchen though?" Asked Stress.
"I don't think you need a stove for ice cream," Zedaph stated as he passed on the appetizers.
"You have a point there!" Stated stress as she started to eat ice cream.

When Zedaph got to Scar it was a bit disappointing.

"Sorry Scar about only having one apple, I ran out," Zedaph apologized.
"Well I could give you the rest of my carrots Scar," Grian offered.
"I owe you one Grian!" Scar stated eagerly.

And so the chefs Iskall, Cub, and Biffa brought the main meals. It was pretty festive and everyone made sure to honor the dead. At the end everyone was in a happy mood. So, everyone went too their rooms to sleep

"Ugh... I might have eaten too much..." Grian groaned, "I'm just gonna go to sleep..."

Cub PoV

"Where's Grian and Scar?" Cub wondered out loud.

Cub then met up with Iskall and Docm and they decided to find the missing people together. When they got to Room 1 Cub got a bad feeling but brushed it off. The sight Cub saw was a nightmare.

"A Body Has Been Discovered Everyone Please Gather At Room 1!"

There sat Scar on the lowest of the 13 seats. His face was very pale and it seemed that he coughed up blood.

Evidence #1 The original rules
It seems as Kokoromono left out a couple rules namely
Rule 6: If the Mastermind is chosen as the killer then all the survivors live with the exception of the Mastermind including the actual killer
Rule 7: If the Mastermind dies then all the remaining participants escape into the outside world

Evidence #2 Poison
Scar had no external wounds so it's very likely Scar was poisoned.

Evidence #3 Masterkey
A Masterkey was found it's very likely the killer used said Masterkey

Evidence #4 Sick Grian
Grian was apparently got sick after the feast something Iskall confirms

Evidence #5 Grian's Motive
The motive was apparently targeted towards Grian. Grian confirms that he knew the man in the video. Grian does indeed have the motive to kill.

A/N: Sorry Scar but your death was planned for a while. Also for those of you who don't know the current Fourth Trial was originally planned to be the third but I decided against that some time before the Second Trial. Yeah a lot of my plans changed for this story. I might show off what was planned in an Extras Book if you want. I believe I still have my original plans though I might be wrong.
