It's canon! No, it's an AU! It's – it's a canoe! Oh, hell, just read it! Well basically, Rodney is in a coma and thinks he’s a fashion expert and John goes into his mind to get him out.
In which Rodney is a famous TV chef and John is a lobster fisherman. I am not even kidding.
Canon AU loosely based on the 1945 film in which Spencer Tracy is a scientist working on a secret government project and Katharine Hepburn is the widow who enters into an unusual marriage with him.
