I thought he was going to become a ninetails. I can switch them though I have an idea for them. When he fights he uses the swords to channel his powers. It is like focus for the magic he wields. Unlike his sister Rowena who uses elemental magic to enhance her fighting skills, Jason uses his swords to cast spells. Jason can not speak about the orgization like Sam couldn't, but can not use his magic against them either. They made sure of that by infusing the crystal into his hands. He was made to hold until it fused with his skin and magical signature. He has also become a heavy drinker because of some of the things he was made to do before the crystal was introduced.
