When Peter was at home, Pepper and Tony stood worried in the living room.

Peter put down his backpack and told them to sat down on the couch. He self sat on a chair, by the table.
"So?", asked Tony, "What did you found? What's with Morgan?" "At first, can you look for flaked skin on yourselves? On the arms, especially?" They nodded and rolled up their sleeves. "Nope. Nothing", said Tony. Peter sighed relieved. "Okay?", wanted Pepper to know. "Yeah... I think it's the Bryonium. A serum, developed by Dr. Bryat. He injected himself with it. The side effects were flaked skin and today he got crazy! Well, I think it spreads through the air. Morgan came to me, in the evening, 'cause she couldn't sleep.
Now, Savin and Riri are sick, too!"

"Okay... Wow", meant Tony impressed. "So, you think, it's a infection?", asked Pepper. "Yeah. He asked, if I could lift the table. I didn't cause I didn't wanted to make him false hope..." "So? What can we do?" "I dunno. At first, stay away from Morgan. I'll take care of her. I don't know, if it's a one-time-infection or something else", said Peter. "You sure about this?", asked Pepper. "Yeah."
Peter took his backpack and went upstairs. He knocked on Morgan's door. "Morgan?", he asked inside, "You alright?" "Peter! Yeah, I'm good." "Can you look, if you have flaked skin on the arms?", he asked. She nodded and took of her shirt. "Yeah... My arms are peeling themselves", meant the girl, "What is that?" "Ehm... Let's just call it an infection...", said Peter, "Oh, ehm, Morgan? Do you have Prim's number? I gotta call her brother..." "Yea. On my table is her number... In the book", she said and pointed on her writing desk. Peter smiled thankful and took the note with him.
In his room, he called the number.
After a bit waiting a woman picked up: "Hello?" "Hello. Is Savin there?" "Yes, one moment please..." Peter heard indistinctly talking, then said Savin on the phone: "Hello?" "Ah, Savin! It's Peter. From the internship..." "Ah! Peter. Hi. What's up?" "You're sick, right?", he asked. "Yeah... Nausea..." "I know what it is! Riri is sick, too. It's Dr. Bryat's Bryonium. It spreads through the air, I think." "You sure about this?" "Yes. My sister is infected, too." "Okay..." "Could you please quarantine yourself and check, if your family has flaked skin on the arms?" "Why?" "As long as we don't know anything about it, I think, it's better not to meet somebody..." "I don't know...", said Savin, "I can check my family, but quarantine?" "We don't understand the serum yet... Dr. Bryat literally got crazy today! He threw things on the lady in the reception!" "What?!" "I should inject him with the Bryonium. He went, to run some test and the next thing I knew, was that he threw things at the woman and that he had super strength!" "Like Captain America?", Savin asked. "No, not like that... He just went crazy!" "Wow!" "Wait... I'll give you my phone number, that you can text me, when something is..." "Okay." Peter told him the numbers and they talked a bit.
When he hung up, he knew, that Savin will check his family and tell him the results.
