Does anyone know why Lloyd keeps trying to make Arin seem as if he has the greatest potential out of the ninja?

I recently watched dragons rising and besides s3 I loved it so far but I'm scared for the future as the stroy keeps trying to push this narrative that Arin has the greatest potential yet I don't think I see a reason why. With lloyd the golden weapons reacted to him and there was whole green ninja prophecy but with Arin all he seemed to do was use a wonky form a spinjitzu without learning from anybody Can you guys visualize what that potential is? I personally have my own theories of riyu...
