same script for two scenes, how can i call a function for particular scene with out affecting that function for another scene??

same script for two scenes, how can i call a function for particular scene with out affecting that function for another scene?? In below code, second scene will load when button clicked, i want to call DisplayInRandom() function for second scene in OnMouseDown(). Initially i should also call DisplaysInSequence() function for first scene in OnMouseDown(). But i'm able to call only one function for both scenes in OnMouseDown(). I want to call specific function for particular scene by attaching same script for both scenes.

using System.Collections; using System.Collections.Generic; using System.Linq; using UnityEngine; using UnityEngine.SceneManagement;

public class DisplaySingleImage : MonoBehaviour { public Sprite[] Images; List Sprites; List Scenes; int NextValue = 0;

 void Start () {
     Images = Resources.LoadAll<Sprite>("Sprites");
     Sprites = Images.ToList();
 }

 private void OnMouseDown()
 {
     DisplayInSequence();
 }
 
 
 public void ToRandom()
 {
     SceneManager.LoadScene("DisplaySingleImageRandom");
 }

 public void ToSequence()
 {
     SceneManager.LoadScene("DisplaySingleImage");
 }

 public void DisplayInSequence()
 {
     NextValue++;
     if (NextValue == Images.Length)
         NextValue = 0;
     GetComponent<SpriteRenderer>().sprite = Images[NextValue];
     Debug.Log(Images[NextValue]);
 }

 public void DisplayInRandom()
 {
     if (Sprites.Count == 0)
     {
         Sprites = Images.ToList();
     }
     NextValue = UnityEngine.Random.Range(0, Sprites.Count);

     GetComponent<SpriteRenderer>().sprite = Sprites[NextValue];
     Debug.Log(Sprites[NextValue]);
     Sprites.RemoveAt(NextValue);
 }

}
