" Stay away from her." Andy couldn't let any of them lay a finger on Esme after what  already happened  to her. His father's nearly uncontrolled blast could have killed her.  Then the telepath Andy loved had been thrown through a portal by Clarice and John.  Then to finish off the pain and knock her out Lauren created a barrier which Esme landed on roughly.

By the time he reached her blood was visible in her hair, on her shirt collar and she had butn marks and bruises every where on her exposed skin.  Andy hated himself for getting here too late to stop any of this.

He saw them do nothing and he was angry. His family including his mother who had more then enough medical experience to save Esme weren't doing a thing to save her. They were ready to leave her to die and drag him back to the Underground. 

His tremor sent his father and sister to the ground. Coldly he turned to face John and Clarice.  John tried to grab his wrist and Andy sent him through a couple walls.  Clarice he knocked out quickly. 

He felt for Esme's pulse and was glad it was there." Help her!" He didn't ask or plead for her to do it. It was a command. He made the entire place shake." NOW CAITLIN!" He ordered.

He looked at Esme." Your going ti be okay.  I'm not letting anyone hurt you.  They don't mean a thing to me if they do something like this. I would do worse to save you."
