Remember, we left Catherine alone when she was ten.

Yeah. But we have to make sure that Mark knows what to do in case of emergency.

He took part in the first aid training program last month and passed the exam.

Hmm, you have the point.

Let's create an emergency situation for him.

Then he'll have real-life experience instead of just theory.

Shh... keep the plan between us.
