This is a neat episode that has a brief flashback to 994 A.D. where we see the introduction of coldstone and a young Demona. But I think I noticed an error I'm not really sure. In the flash back we see Demona wearing earings. I thought we didnt see Demona with earings until the present time line. The episode also references Frankenstein where Xanatos screams Its alive, alive when they bring coldstone back to life.
