Jen suddenly rapidly blink and got Martin in a strangle hold. Jen whispered to Martin, "Apparently due to the cause of my transformation, I am immune to other magical adjustments that I do not allow. Meaning that unless the stone is used or objects and/or powers created by the stone are used I can not be manipulated." Jen learned this when Martin tried to manipulate her she also learned that this was only due to her being the official inheritor of the stone. **Also as such she could summon the stone if it got into someone elses possession, unless wishes used while the stone was in their possession prevented it.** She summoned the stone and said, "I wish everyone but me until I wish otherwise was frozen in time. I also wish I know exactly why I ended up like this and how I can become a guy again."
