Where did you get the seeds from?
I was looking around on the hottest pepper website and it seems like they only sell 2 types of plants, Bhuts and Habs. The first picture really has more of a hab shape. It is possible that you got a few hab seeds in your pack or that you have a cross breed that is showing more hab qualities.
Or a bhutanero!

I have some red bhuts also from Dave from ebay which everyone says is reputable, but that is not showing any pods yet.
