Will had yelled very loud "what?", He was standing there looking at the phone held in his hand, and the other was a punch. Natalie gave Meggy a questioning look before approaching her boyfriend.

The doctor was stuck and she realized that something bad had happened.

- My brother ... my brother is ... he's been poisoned,- he said later. He was in shock.

- Okay, don't worry, we don't know how bad it is. And in any case Jay will make it, I am convinced ... he is strong. - she said to Halstead as Maggie approached too.

- I warn Dr. Marcel that the ambulance is about to arrive. - said the nurse

- Thank you,- Natalie told her, taking the place of the doctor who was unable to speak at the moment. He was immersed in her thoughts. Everything could be expected, but he would never have thought of a poisoning.

Shortly thereafter, the stretcher came in with Dr. Halstead's brother and when Dr. Marcel approached the paramedics began to provide what was the information they were in possession of.

Dr. Crockett immediately connected the young detective to a respirator and ordered generic and specific tests.

It was poisoning that was sure, but you had to understand at home he had been exposed and how he had ingested it.

Once the boy was stabilized, Marcel stopped to talk to Antonio, he wanted more information to narrow down the field on the type of poison and how he had ingested it.

Unfortunately what the older detective told him didn't help much until ...

- He was sick since this morning I think. He didn't even want to come with the rest of us to have lunch. He said that he received a cake from his brother as a gift and that he had eaten almost everything, it was his favorite and therefore at that moment he was full. I saw him put a box in his desk drawer. It could be the one containing the poison.

- Could ... could you have it for me? - asked Dr. Crockett.

- I'll make a phone call,- said the other.

- Ruzek,- he replied

- Hey Adam, it's Antonio, you have to see if there is any package in Jay's desk containing a cake, it should be a gift. Put your gloves on before you touch it. -

- I'll take a look, wait,- the policeman said while he was wearing them, - but why the gloves?-

-Just do it,- replied the other.

- Yes, here I am, don't worry. Here is a little packet of brownies. -

- Here you have to take him to Med right away. Immediately. - said the detective

When the call was over, he found Dr. Crockett to tell him that the package had been recovered and that they were taking it there.

- As soon as your colleague arrives, deliver it to me immediately. I will have it analyzed. - Marcel said.

Then Antonio went to the door to wait for his colleague and in the meantime he called Voight to inform him of everything that was happening.
