Very interesting observation ONCEmusicfan…I <3 Rumple+Cane too! I think it gives more depth to the characterization of Gold.... I think Rumple literally CANNOT heal himself, because the dark powers prevent this, the dark arts come with a price and I guess that price is the deterioration of his soul and body (crocodile/beast) I guess it could be like the genie, that he cannot wish himself free, someone must do it for him, so rumple cannot make a curse to get rid of the BAD things that come with him being the dark one. MAYBE but i could be wrong....
