Is OnEnable fired right after Awake?

Scenario:

I have a View that's supposed to subscribe to an event from a controller to update a Text.text with a score only if the score in the controller gets updated.

For this I make an event in my controller (called BattleInstance) and make my controller a singleton in Awake():

 public event System.Action<int> UpdatedPoints;
 
 private void Awake()
         {
             if (instance == null)
             {
                 instance = this;
             }
             else if (instance != this)
             {
                 Destroy(gameObject);
             }
         }
 

In my BattleViewController I want to make sure I subscribe and unsubscribe (Bye,Bye memleak ;) ) in the OnEnable() and OnDisable()

 private void OnEnable()
     {
         BattleInstance.instance.UpdatedPoints += this.UpdatePointDisplay;
     }
 
     private void OnDisable()
     {
         BattleInstance.instance.UpdatedPoints -= this.UpdatePointDisplay;
     }

Now when I run this I get this error

NullReferenceException: Object reference not set to an instance of an object BattleViewController.OnEnable () (at Assets/Scripts/BattleScene/ViewControllers/BattleViewController.cs:44)

when trying to subscribe because apparently the OnEnable in my ViewController is called before the Awake in my Controller. :(

Subsequently of course, when my Controller fires the event in the Start() to initialize the score display as 0 I get:

NullReferenceException: Object reference not set to an instance of an object BattleInstance.Start () (at Assets/Scripts/Administration/BattleInstance.cs:38)

EDIT:

To specify my question(s):

• Do I understand it correctly that the OnEnable is fired right after an object's Awake? So the order being Object1.Awake() | Object1.OnEnable() | Object2.Awake() | Object2.OnEnabnle() | Object1.Start() | Object2.Start ?

• How do I in my Object1.OnEnable() make sure that Object2 is Awake?
