Untrue, Han ans Leila had three kids. A daughter and two sons and if I'm not mistake one sibling kills the other. And Kylo isn't even BEN, he wasn't the one that turned evil. I may be a bit wrong, but grrrrrrr.
THE FEELS <<<this is literally the only reason I'm watching Rebels season 2 (+Rex) (Rebels just doesn't have that same feel to it as Clone Wars) this is what makes season two final so sad they were master and padawan.
