When they entered the kitchen

“Huh! What happened? How did you get hurt?” Emily asks jack

“Mom, Sis threw a water glass on me !!!”

“Well technically, She threw a robot toy at my glass and that's when the glass burst on my hand.”

"NO, MOM! 

I DIDN’T, HE IS LYING !!!" Daisy exclaims.

But what are you both doing in the kitchen??

Mom, I was just drinking water, my sister came and threw her robot toy on the glass and this happened.

Ivan thought:

"Huh, why is a girl playing with a robot in the first place? I knew that my sis was a WEIRDO !!!" Ivan thinks

Ivan was accessing the situation that's when he realized that something was amiss.

"I know that she is a bit weird but she is kind. Due to my ability to think, I can easily find the personality of the kids who play with me." Ivan thinks

In other words,

There is an 80 % probability that she didn't do it, a 15 % probability that she did it by mistake, and a 5 % that I am wrong and she is evil.

I only met her for 27 min 12 sec, So I guess I could be wrong but let's examine the situation first.

He said that he was drinking water when she threw a robot toy but there are no water drops on the ground.

But this is not enough clue I need more to act in the right position.

huh…

WAIT A MINUTE!!!

Why do his lips and the small hair above his lips also not have water drops? I am sure he didn't have time to wipe his face.

He said he was drinking. If the glass burst why there is not a single mark on his face.

What's more, is that he has ink on his left palm which means he is lefty. So why was he drinking water with the opposite hand?

And why didn’t he tell the servants to bring him water and why didn't he even put his bag down on the sofa before coming into the kitchen?

All these clues points to a single thing that

HE IS LYING!!! "But well he is quite a high IQ kid' he grabbed the attention by telling the wrong thing first. (lie - Daisy threw a water glass on him)." Ivan compliments jack in his mind unknowingly.

But can this small kid, access the situation even in pain, I don't think so.

Oh no! I am feeling sleepy, this body of mine…

I gotta do something before I sleep.

I need to help her but how?

By seeing mother glaring her I am sure she is going to punish her.

His mom spoke,

Jack, are you kidding me?

It is sauce on your hands mixed with water, and the cap of the ketchup is open too.

“No mom is wrong, it is real blood.” Ivan thinks

{Jack’s perspective}

I'm going to discipline my sister. At school, I warned her not to approach me, but she still spoke to me. I don't get the chance to meet her at school because the departure of elementary students is earlier than mine.

I told mom to not get her admitted to my school. Let's do this; I'll ask my mother to send her to boarding school as a kind of punishment.

After some consideration, he devised a plan.

"To solve the primary issue of fake blood, let's stop the car at our hospital and get real blood there," he tells the driver

Now that I think about it, today is our family's celebration of our new brother, and it will be great to use him as a slave for a year or two like my older brother used to use me.

Hoho.
