Had to get a rec in once I saw your request for Groo/Wes fic. This one's splendidly well-written, and I haven't found any other work that focuses on Groo in so much depth: "Just Somewhere" (http://tasteofpoison.inkubation.net/fanfic/viewstory.php?sid=151) by Arsenic, AUish. Plus, vivid and respectful portrayals of Cordelia and (more briefly) Fred, while letting Groo and Wes have the space they need to move on. Further comments on your own lovely "Failure to Communicate" soon!
