Ever since MSN revealed that there was an upcoming episode about Betty and Ice King transforming, everyone has been asking countless times to the crew if it is real, only to get the answer of "no comment." Well, you're searching is over as I have indirectly received the news via Jeremy Shada on Facebook that it is real!
And here is the proof: http://m.facebook.com/story.php?story_fbid=585171714897495&id=255032867912500&comment_id=72836066&offset=0&total_comments=1¬if_t=share_comment&ref=m_notif
You all can thank me later. But thank Jeremy too! :D
