Wait I have another theory!

When Colin left Rumple, because Pan said that Rumple's father had left him, he instead turned himself into Pan using some kind of spell (maybe from Tink). He instead became a friend of Rumple at first but afterwards they became rivals, as they are now. And then the rest that Rumple stabs Pan turning him back into Colin.
