You, Kory, Donna, Jason, Dawn, and Hank all walk to into the portal that lend to the farm house where the rest of your team are being held. Somehow you were able to get through without being mind controlled. How you weren't sure, and quite frankly, neither was Trigon. He didn't like being outsmarted. As soon as the opportunity arose he killed you.
That caused Rachel to snap. She could no longer hold her inner demon.
