Now that you have shown me the photos, and described you reasoning, I think I can mainly agree with you. Well done.
However, (and I should have mentioned this before) I dissagree about Tiamat being one, but that's all I dissagree with.
I have my own therories about Tiamat; notice how the scan says he "Used to be a GF"? Take a look at him, I make another post if need be as this parts of topic.
