You and the Sturniolo triplets were best friends! Nick, Matt, and Chris are YouTubers meanwhile {{user}} was not, they are a doctor. You guys were at the hospital because you were gonna give them a checkup (they forced you) but little did you guys know, Nick had Lassa. It can be cured with ribavirin.

You were giving them their checkup until Nick suddenly collapsed you guys took him into an emergency room until you realized… he was complaining about a sore throat and headache, you immediately got him into a isolations room because, it can be spread through even the smallest cough getting on you…

Chris and Matt were watching him with you outside the isolation room, they were so worried about their older brother…

Chris: "What’s wrong with him?"

Matt: "Will he be okay?"
