Need help completely disabling a script

 #pragma strict
 
 var talkLines:String[];
 var talkTextGUI:UnityEngine.UI.Text;
 var textscrollSpeed:int;
 
 private var talking:boolean;
 private var textIsScrolling:boolean;
 private var playerScript:UnityStandardAssets.Characters.FirstPerson.FirstPersonController;
 private var currentLine:int;
 
 function OnTriggerEnter(col:Collider){
     if(col.tag == "Player"){
     playerScript = col.GetComponent(UnityStandardAssets.Characters.FirstPerson.FirstPersonController);
      Debug.Log(playerScript);
      talking = true;
      currentLine = 0;
      //talkTextGUI.text = talkLines[currentLine]; //STATIC
      startScrolling();
      playerScript.enabled = false;     
      
     }
 }
 
 function Update () {
     if(talking){
         if(Input.GetButtonDown("Npcmt")){
             if(textIsScrolling){
             //display full line
             talkTextGUI.text = talkLines[currentLine];
             textIsScrolling = false;
             }
             else{
                 //display next line
                 if(currentLine < talkLines.Length - 1){
                 currentLine++;
                 //talkTextGUI.text = talkLines[currentLine]; //STATIC
                 startScrolling();
                 }
                 else{
                     currentLine = 0;
                     talkTextGUI.text = "";
                     talking = false;
                     playerScript.enabled = true;
 
 }
 }
 }
 }
 }
 
 function startScrolling(){
 textIsScrolling = true;
 var startLine:int = currentLine;
 var displayText:String = "";
 
 for(var i:int = 0; i < talkLines[currentLine].Length; i++){
   if(textIsScrolling && currentLine == startLine){
 displayText += talkLines[currentLine][i];
 talkTextGUI.text = displayText;
 yield WaitForSeconds(1/ textscrollSpeed);
 
 }
 }
 }

Above is my NPC talking script in Unity.

 #pragma strict
 
 var script : NPCscript;
 
 function Start() {
 script = GetComponent(NPCscript);
 script.enabled = false;
 }

Above is my disabling script for the NPC script. The problem is that when I disable the script it doesn't fully work and it shows the first line of dialogue and you can't continue the dialogue. I want all the dialouge to be fully disabled and not to work. The variable talking and the variable textIsScrolling become true when the script is disabled when I talk to the NPC and I think that that is the problem.

Thanks, ~Jordan

P.S Both of these scripts are in JS.
