Freygar was lurking around Casper during that fight. He barely could believe that the White warrior found a way to beat two copies of him at once. He was sure in the start that it would be enough, but the way that the soldier could deal with pressure and extremely dangerous situations was simply amazing.
At that moment, he was facing a formidable opponent that, willing him or not, was way better. If not for his resources, Freygar would have been defeated a long while ago, maybe even in their first battle. And even with all his equipment and preparation, Casper could counter him completely, no matter how much harsh the situation was.
