We had to wait 7 months to find out....lol I will tell you... in the books ....Valentine only loved 1 of his children and that was Jace. He hated Clary because he blamed her for taking Jocelyn away from him...and Jonathan was a demon...Jace he couldn't make him bad no matter how hard he tried...so the only one he loved was the one who wasn't actually his. Season 3 is even better..so...how could you wait :) 22 more episodes!!!!
