Mom is now making Elle do things, maybe, just maybe she knew that there were problems between them and wanted to help. But that hug was perfect. It looked like both of them had been wanting to hug for sometime.
Hug is good but honestly they need to talk about things in a proper way so next time such won't happen again .but I hope when the time comes for the truth he will still stand by her by understanding she did all she did to avenge her parents.
