The last thing that Damien was able to do to both of them was the Cold touch. Remember that thing that would slowly kill Henry and stunt Morgan. But now Henry knew something and he had made allies like Peterson he was a doctor for humans and magical people. He discovered that he could survive if he went dark as in evil and tainted his soul. But Henry was not willing to do that for fear of not being able to come back. Only 3 things could make him do that either he choses to, when in his death bed it just happens which was unlikely but could still always happen, or a dorety which is a magic process that Henry and Morgan had only done once to escape the first time they were taken. You take a metal any type of metal that kills the intended victims it has to be done with two people and you hold the material in your hand and it can kill thounds if close enough. They used it in Damiens men, they can only be killed with silver. The dorety almost killed them both last time. But they were weaker. If they were to do it again it could turn him dark or kill him since he is very weak same with Morgan but she is stronger than him so not likely.
They escaped using whatever strength they had left. And went to see who by the way was in New Hampshire which is right next to Maine but said nothing of the Cold touch and just had the wounds mended. And they stayed in New Hampshire. They even got plain Black butterfly tattoos in between their shoulder blaids symbolizing transformation and new beginning. The got a apartment in New Hampshire and stayed close to the doctors.
