I feel JK’s personality won't change. But the way he treats Dan will definitely change. He will love Dan and make up for all the things he did to our baby. And we all know Dan will forgive and love the dude lol.
And I've also noticed that some of his behaviors are abnormal, maybe it's a trauma from his childhood perhaps? It seems he's new to the emotion ‘Jealousy’ so he acts on it in the most unreasonable way possible. Hilarious.

I kinda give up on jk already...I don't think that man can be fixed in any way , I have this one tiny bean of hope were Dan goes off and leave and then jk gets depression , car accident , loose every match , loose his title , break an arm ....and even after those I'm not entirely sure he'll be fixed .
