"Wait, what if he was poisoned while he was carrying poisons from the lab to the main hall trolley? That would have been a great opportunity" said Galtomor.

"Why then? Wouldn't it be easy for people to notice if he was forced to drink? Since Tenma would tell if someone forced him to do something. “ grumbled Salim.

"They didn't have to force him to. Maybe ask Tenma to drink one of the chemicals that was being carried, see how it tastes. They just added CycloniumX into it." explained Galtomor.

"Your theory makes no sense. Because the chemicals there were all harmful. Tenma knew what all the chemicals did, so why would he drink one of them? Besides, Tenma himself is a chemist and was aware that someone stole CycloniumX. The culprit has to have done something other than just approaching him privately and asking him to drink a suspicious liquid." explained Salim.

"Yeah, hehe. But we don't know what and when he was drinking and eating privately tho." complained Galtomor.

"Was he maybe injected by the poison? With a needle perhaps." suddenly asked Galtomor.

"Probably not, considering he had no wounds other than the stab wounds. A needle mark would be visible." said Fushichin.

"Plus, he would probably make a fuss and argue with the attacker if he was shot with a needle." said Klancy.

"Yeah, I just don't know when it could have happened." grumbled Galtomor with disappointment.

"Well, the obvious time where he could have been poisoned by consumption is the dinner” said Hellen confidently.

"But how tho? I remember reading from the truth files that Tenma didn't even eat any food during that time. How would he be poisoned?" asked Galtomor with surprise.

"Well, obviously, he didn't eat anything. But he could be poisoned from drinking the tea" said Hellen.

"Yes, yes. Maybe the cups themselves could be poisoned. If you remember the Tenma family eats from different cups. So maybe if they just poisoned Tenma's cup." said Fushichin with excitement.

"No, I don't think that's possible because the cups were cleaned by Jude and Yumiko while Marian watched them. They were keeping a close eye on each other. Afterwards the cups were delivered straight into the dining hall where everyone was." said Galtomor.

"I mean. It could be possible that Jude, Yumiko and Marian were working together." grumbled Fushichin.

"You're that doubtful of others?" asked Hellen with a frown.

"Hey, it's a possibility. The three of them hid about the attempted murder beforehand, haven't they. Who says they aren't capable of killing Tenma while working together." said Fushichin with grumpiness.

Unauthorized duplication: this narrative has been taken without consent. Report sightings.

The detectives shared silent glances.

"The possibility isn't zero. I will give you that. But I will also say that the possibility of a single culprit is a lot higher. And we did corner them previously. After they spilled the beans, they seemed relieved. I don't think they were hiding more grave truths from us." said Klancy.

"Ugh, fine, maybe you're right." grumbled Fushichin.

"I do think Hellen's theory of the drink being poisoned makes the most sense." said Klancy.

"No, it doesn't. If the drink was poisoned, how was everyone else alive? They all drank tea, they all should have died from the poison." yelled Galtomor with frustration.

"Yeah, but you're forgetting one thing. The antidote SteadyY neutralizes CycloniumX." said Hellen.

"Oh, that's right. But do you think everyone miraculously took the antidote?" asked Galtomor.

"Yeah, I guess so. But I don't think it's miraculous. More like, calculatively." said Hellen.

"Calculatively huh." pondered Galtomor.

"Yeah, probably the culprit set it up. Where do you think SteadyY was?" asked Hellen.

"Hmm...I think it was in the spaghetti?" asked Galtomor.

"Yeah, that was my guess too." said Hellen.

"Makes sense. Since Tenma didn't eat the spaghetti, he only drank tea." said Fushichin lightly.

"I see. The culprit could have successfully targeted him only if they knew that Tenma was fasting that day. They had to have known that Tenma wouldn't eat the spaghetti." said Klancy.

“If I remember correctly. The spaghetti and tea were made by Yumiko and Jude. It would be easy to point the finger towards them. But I don't think they poisoned the tea in the kitchen at 14 pm. Jude and Succi both drank from that tea at 15 pm. They didn't eat from the spaghetti. Jude went to the library after that, then he probably stopped Marian from attacking Yumiko." said Klancy.

"And according to Succi's alibi. Succi said he took a shower" said Fushichin.

"As you can see, both of them didn't die." said Klancy elegantly.

"But Succi was the one left alone in the dining hall. Quite suspicious if you ask me." said Fushichin with a frown.

“It's too early to point fingers. In any case, we know that the tea and spaghetti were left alone from then until Yumiko and Jude came back to the dining hall." said Klancy.

"Right." said Salim with a frown.

"W-Wait, hold on. Have you guys not noticed something strange?" gasped Galtomor.

"About what?" asked Hellen clueless.

"Our theories! There is a hole in it. Most specifically the theory of the antidote being in the spaghetti. Because if that were the case, certain someone should have died from CycloniumX. But that person didn't." yelled Galtomor.

The others looked at him cluelessly. Galtomor rolled his eyes and said "Joseph didn't eat from the spaghetti."

"Oh, that's right! I almost forgot." yelled Hellen.

"He should have died, but didn't. Which makes me think that the antidote wasn't in the spaghetti. Or at least there was another reason Joseph didn't die." said Galtomor with a meticulous face.

"Yeah, you're probably right. And I think I figured it out." said Fushichin brightly.

"You did?" asked Salim.

"Yeah. Joseph didn't die because the antidote was also inside the guest cups." said Fushichin casually.

"Really?" asked Galtomor with a surprised face.

"I mean, it's impossible to know for sure now. But it's probable. The spaghetti and the guest cups both had the antidote. That way, they can only target Tenma. Since there is a chance that the guests might not eat their spaghetti and die, our culprit safe proofed their plan." said Fushichin.

"But they couldn't safeproof the survival of the main household members?" asked Hellen with doubt.

"Hey, you win some, you lose some. It's probably a risk our culprit was willing to take." said Fushichin carelessly.

"I guess that does make sense. The poison would lose its effect when tea is poured into the cup that has the antidote." said Galtomor.

"Yeah, good job." said Salim.
