User blog comment:Ajrep1994/Yang and Ruby are half sisters/@comment-5217560-20140724024022

It's about time he confirmed it. I thought it was pretty clear that they were half sisters just from everything he said previous to that tweet! But I'm glad it's finally been put into the light! Yaay. Now I wonder what were the circumstances between summer rose, their dad, and yang's mom. That will be very satisfying.
