After a season that I thought was dragging, The Flash has finally hit its stride again. It was a very poignant to see Frost examining who she really was and why she ever came into being. From those first scenes I had a creeping feeling of how this would end, but I stayed to see how they played it out. I think I also see a way for her to come back, and that was by the very connected grief that Caitlin had for her. That cry seemed to sound across the ages, and that could be powerful enough to do anything in The Flash world. If Danielle Panabaker was tired of 2 roles, I understand. But I do hope we get to see Frost again someday soon. She is a big part of team Flash.
