Jay is at a security desk. He is passing his bag, his phone, and an ID card to an unseen person wearing a military uniform.

He steps into a full body scanner as the military personnel on the other side of a window rummage through his belongings, and check his credentials. On the way out, he is passed back his belongings, his ID, and a different, bright yellow phone. It's implied that his personal phone is being kept behind the security gate.

He jogs through the halls, trying to reach his destination quickly.

He swipes his ID at a door, which clicks open, and he enters. In a locker room type area, he exchanges his hoodie for a lab coat. Seen behind him in the mirror as he gets himself ready is a blast door with black and yellow warning stripes on it.
