   Summary

   [This is a Caitlin Snow x Male OC (with connections to halo) story.]
   [This story has a very loose canon way of story telling so it won't be completely accurate to the CW Flash.]

   Caitlin Snow has recently gotten control of her alter ego Killer Frost and yet, she feels like everyone at Team Flash are waiting for her to snap and go back to being evil.
   That is until someone named Mark Foster enters her life after Team Flash finds him on their doorstep, covered in his own blood and a faint blue glow coming from his fingertips.
   Now Caitlin must help Mark with whatever is happening to him and also keep herself from going back to letting Frost being evil.
