That perception vs actuality idea sounds like a lot of fun to play around with, it almost turns MC into an unreliable narrator (the most interesting kind IMO) and could spring board a whole host of situations that can be discussed but I won't in fear of going off in a boring tangent.
To address the 13 year status quo dilemma what if it was the lack of MC presence that established it? Maybe MC wasn't raised near the mum or the aunt and it’s in his action of seeking them out that he tips the balance of power one way or the other causing the explosion. Maybe one needed to protect him or was distracted by him reappearing in their lives giving the other creating an opening that causes the explosion ect...
Another reason he could strive to be the best is classic abandonment issues.
Just a thought, I don't mean to run ahead with your story or ideas.
