"Hey Wait!" Dean called starting after them with Sam after seeing Castiel had his angel blade out.
Castiel had a confused look on his face as Naomi told him to kill them both before they could get away. Suddenly he disappeared and reappeared in-front of Elly and Samandriel.
Elly had been using both arms to hold Samandriel up, having her right arm under his shoulders and her left hand on his chest as she led him to the car, but seeing Castiel appear in-front of her and let her left arm drop and an angelic blade slipped out of her sleeve and she gripped the handle not liking the fact that she would have to fight Castiel. She looked at Samandriel out of the corner of her eyes and saw that he needed attention and quickly.
Samandriel lifted his head, he had been running on the pure adrenalin of the situation when he had tried to talk to Castiel but now that it was gone even that simple movement was hard. He saw Castiel standing in-front of them ready to attack and said. "Adnachiel, go." He told her Castiel was a Seraph now just as Elly had been before she fallen, and though she had access to some of her powers from wearing her grace around her neck she wasn't as powerful now as she would be if she had taken her grace in. He didn't think she had much of a chance of beating him and he didn't want her to die because of him.
"Samandriel, just stand their quietly and reserve your strength." Elly told him in a soft tone and then turned her attention back to Castiel just as Sam and Dean came around the corner behind them and said to him. "Castiel, are you really going to fight us? Going to kill us in cold blood? You have enough death on your hands." She told him. "Think, how would Anael feel about this? The fact that your were going to kill your student and hers? That you were going to take the lives of two more siblings?" She asked.
Castiel got a confused look on his face and started to see the truth in her words, and started to wonder why was he doing this? He didn't want to do anymore needless killing. He had come here to save Samandriel and now he was about to kill him and Adnachiel. He put his hand to his head, his mind fighting against Naomi's control. blood leaked out of the corner of his eyes and his nose and he brought his other hand up to his head partially coming back to his senses. "Go." He said in a strained voice as Naomi yelled for him to kill them, getting more desperate each time she commanded it. "Now!" He old them putting Anael into the front of his mind, using her memory to fight against Naomi's control.
Elly nodded and rushed past Castiel as best she could supporting Samandriel to and got him into the passenger's seat of her car before going over to the other side and getting in, she turned on the car and drove away faster then she probably should have.
