Weird, seemingly random scene. “Hello? Anyone here?”

When they arrive at the hearing to determine Raymond’s future, they enter and it’s sort of furnished like a large house or something, but I guess the psychiatrist’s office is in there somewhere. They don’t see anyone, and Charlie is wandering around yelling “Hello?”. Why? Why in the world is that scene there? In the next scene they have apparently found the office and they are in there talking to the psychiatrist. I kept expecting it to pay off somehow but it did not. SO random.
