It was a good thing that Legolas had grown more of a tolerance to pain, especially after the conditioning he'd endured at Jason's hands. While his bodies had changed, his mind stayed the same and he could brace himself against it. Especially once he felt the metal moving, bending, and the tubes pulling at his neck.

His hand moved, grasping Thranduil's clothes. Not pushing him away but for the sake of holding something and having something else to focus on as the collar came undone. First green fluid flows out of his neck where the tubes had been and then blood which Legolas quickly grasped at his neck to slow the flow of.
