Something inspired by this fanart (http://viviena.tumblr.com/post/153454305098/attacking-a-man-traveling-with-a-devoted-obscurial). Basically protection and h/c, but Newt is the one hurt and Credence doing the protecting/comforting. Bonus points if Newt still has to coax Credence into showing himself, and if it especially bothers him that Credence doesn't hesitate to kill people to protect him, but does his best to hide it for his sake.
