She knew Zada and him were working together, but they were only business partners, and Mikki could sense some distrust Gellert directed towards Zada, because frankly the woman was not trustworthy. The second he could sever the partnership, she knew he would. But her talent's were needed.

She murmured a spell and began to direct the flames out the door, backing away and sending it this way and that way, knowing she was adding more and more destruction to the castle.
