"I will admit I rather have a bit of a direct line to the greatest healer." Aziraphale explained, he still hadn't actually told anyone what exactly he was, and he doubted that was something that would change any time soon, but he would of course continue to help where he could. "I am sure healing happens in different ways in some places, but for me it is but the work of a thought." He explained, a none explanation perhaps, but it was as plain as he could put it.
Tea made Aziraphale felt a little more prepared to deal with humanity, or something very near it and he allowed Nyx to tell him a little bit more about when he'd received the injury that had been allowed to linger so long because he hadn't felt like he could ask for help? Or that he just didn't know, it was had to say really. "Do you want the hurt?" He wondered, curious. He knew that there were those who felt like pain was for a purpose, he of course had never been the sort. "I cannot see good reason to allow pain and injury to go on if not."
He sipped his tea carefully and then sat back, "Whenever you're ready," He told him, "If you would just allow me to see what it is we will be dealing with and then we can get to the business of healing."
