When Lucy was being suffocated by the Man...

When Lucy was being suffocated by the Man with a potato sack, and Murphy was psychically feeling her pain, the camera kept focusing on both Lucy and Murphy's eyes, and when it focused on Murphy, little red circles started to form ON his irises. I know its been a few months since the episode aired as I write this, but for whatever reason, that one scene keeps popping into my head and creeping me out, mainly any scene involving the damage of eyes gets udner my skin. But the scene is also making me ask questions at the same time. Were those supposed to be blood vessels about to pop or something, or was it just supposed to imply that as Lucy goes through changes and near death experiences, it affects Murphy physically too?
