Quaternion.Slerp not smooth!

Man, I hate those Quaternions... they always have a problem waiting for you!

Anyway, I have a pilot at a chopper, so I want when the player presses C the camera to use the MouseLook script and look around, and when he is not pressing it to smoothly go back to its starting position. So I wrote this:

 var cockpit = true;
 var third: GameObject;
 var first: GameObject;
 var heli: GameObject;
 var look: Transform;
 
 private var lookAt: Quaternion = new Quaternion(0, 0, 0, 0);
 
 function Update(){

     if(cockpit == true && Input.GetKey(KeyCode.V)){
         first.GetComponent(MouseLook).enabled = true;
         heli.GetComponent(Move).enabled=false;
     }
     else{
         first.GetComponent(MouseLook).enabled = false;
         heli.GetComponent(Move).enabled=true;
         look.rotation = Quaternion.Slerp(transform.rotation, lookAt, 0.1 * Time.deltaTime);
         
     }
 }

It works fine until it comes to move the camera back to its starting position witch moves it instantly, so the problem is at that dam Quaternion! Help, pleaze!!!! :)
