Check if a value is null from another script?

I have a public Follower named CurrentFollower located in “OneFollower”

But in the monster script, i need to access whether it is null in an if statement. Plus this script isnt assigned to an object.

I just need this to work without giving me the exception “object reference not set to an instance of an object”

The answer is in the question.

You want to check if it is null, damn I just answered again…

if(reference != null){
   reference.Method();
}
