how to access parent script from child object with overlapsphere in a multiplayer game

Hello! I have a problem when I'm trying to access a parent script when another gameobject is colliding with the child of the first gameobject. Let me explain this in detail:

This is an online game. The first player has a script attached called DemonSpells and I'm using OverlapSphere to find all the colliders it hits. This is a part of the script:

 void Spell1_Damage(Vector3 center, float radius,string originatorName)
     {
         Collider[] hitColliders = Physics.OverlapSphere(center, radius);
         int i = 0;
         while (i < hitColliders.Length) 
         {
             if(iAmOnTheRedTeam &&  hitColliders[i].transform.tag == "BlueTeamTrigger"){
 
                 Debug.Log(hitColliders[i].transform.root);
     
                 hitColliders[i].transform.SendMessageUpwards("Stun");
 
                 PlayerStats plstats = spawn.redspawn.GetComponent<PlayerStats>();
 
                 HealthAndDamage HDScript = hitColliders[i].transform.GetComponent<HealthAndDamage>();
   
                 HDScript.spellDamage = plstats.stats[2];
                 HDScript.iWasJustAttacked = true;
                 HDScript.myAttacker = originatorName;
                 HDScript.hitBySpell1 = true;
 
 
 
             }
             if(iAmOnTheBlueTeam &&  hitColliders[i].transform.tag == "RedTeamTrigger"){
 
                 Debug.Log(hitColliders[i].transform.root);
     
                 hitColliders[i].transform.SendMessageUpwards("Stun");
 
                 PlayerStats plstats = spawn.bluespawn.GetComponent<PlayerStats>();
                                 
                 HealthAndDamage HDScript = hitColliders[i].transform.GetComponent<HealthAndDamage>();
 
                 HDScript.spellDamage = plstats.stats[2];
                 HDScript.iWasJustAttacked = true;
                 HDScript.myAttacker = originatorName;
                 HDScript.hitBySpell1 = true;
 
 
 
 
             }
             i++;
         }
     }

This code finds the targets and accesses the child of the opponent named Trigger, which holds a script called HealthAndDamage. The player doesn't have any box collider, only the child (Trigger). I can access the Trigger gameobject and apply damage to the opponent but i can't access the parent. I need to access the Movement script from the parent so that I can apply a stun effect. I used SendMessageUpwards and it doesn't work. I also tried to access the parent like this: PointAndClickMovement move = hitColliders[i].transform.parent.gameobject.GetComponent();

This is the method from the PointAndClickMovement script I'm trying to get:

     public void Stun()
     {
 
         Debug.Log("STUN");
 
         previousSpeed = speed;
         speed = 0;
         networkView.RPC("UpdateMySpeed", RPCMode.AllBuffered, speed);
         StartCoroutine(waitForStun(5));
 
     }
 
 
     IEnumerator waitForStun(float time)
     {
 
         yield return new WaitForSeconds (time);
         speed = previousSpeed;
         networkView.RPC("UpdateMySpeed", RPCMode.AllBuffered, speed);
     }

I've tried every possible way to do this but with no luck. I also did this with a Raycast and it worked. But this kind of spell is an AOE(area of effect) and I can't do it with Raycast. Please let me know if I'm doing anything wrong! Thanks! :)
