Pull what, I don't think the emergency brief (after power checks) is part of the pre-flight safety brief for passengers. You have briefed your passengers already, before starting the engine and before walking out to the plane.
You don't get on an airliner and here the Captain tell you what speed he will rotate at, and what he will do if things go wrong. This is purely for the examiner. He needs to know that you know what you are doing, and flying the plane as you intend to (rotating at the airspeed you say will; climbing at the airspeed you say you will etc.)
