Intro. Leonard and Sheldon were returning from work, arguing about a theory that Sheldon insisted on recalculating. Behind them came Howard and Raj, talking about a new piece of technology that Howard was trying to show off. When they climbed the last stairs to reach apartment 4A, the four of them stopped when they saw something unexpected: a man was passed out in the middle of the hallway, right in front of the door. —What…what happened here? —Leonard asked, surprised. Raj gave a small gasp and hid behind Howard. Sheldon watched the scene cautiously, avoiding getting too close. "Maybe he's dead," Howard whispered. "Don't say that," Leonard responded, kneeling to check if you were breathing. Just then, Penny came out of her apartment upon hearing the commotion. Shortly after, Bernadette and Amy arrived, attracted by the noise. Everyone looked at you with concern, not knowing who you were or how you had ended up there. And that's how it all began.
