I would like to know what you guys think.

This animals was born here from two very nice parents. Both parents look like pure T. s. infernalis.
All littermates where normal infernalis. Nearly all have a perfect pattern, one or two have a somewhat distorted pattern and one looks like this.

I'm wondering what your experience is when it comes to variations in pattern within a litter of infernalis.

All input is appreciated!
Sadly, I can't contact the previous owners of my infernalis anymore. I know very litte about their lineage except that they are nice, blotched, specimens...
First picture is the animal (in shed) I'm "worried" about. The second is a typical clutchmate (recently shed).
