So this past weekend I went to my first Repticon (ironically ON my birthday) and the boyfriend surprised me by buying a 3 year old male- was told he's a Cinnamon Pewter, loves to be held, proven breeder, all the nice lines. Then I was talking to a coworker and he stopped me to say that they were the same thing! Google searches give me a bunch of extremely similar snakes or ones mixed with other morphs. Thought I might ask the experts-

Are they the same/different/extremely comparable?
How is it that I got a snake with both, was one parent a Cinnamon and the other a Pewter?

Any info would be great for this novice~
