They'll make an alarm, I think, and they'll know that somebody needs help.

Because it's the hospital, people come in, they're not feeling very well,

and if they don't feel well or they get stuck or something happens,

because they're locked in there.

The doctors and nurses will come and help them.

That's it.

And they have a special key, probably, that lets them open it.

Because it's locked from the inside.

And I think they've got a flashing light on the outside.

You see that light?

I think if someone pulls that red rope, that will start flashing.

Let's go this way, let's go and check in then.

You know how to check in, don't you?

Are you going to do it?

It's what?

And then we're going to sit for ages and wait, probably.

It's exactly time to check in.
