Athena

Carl has problems. His life has crumbled, and he exists now as a shell of a man. His wretched existence is punctuated by the loss of his wife and all of the emotional scaring that has created.

Emily is not well herself. She may be slightly schizophrenic and manic depressive, but she's doing fine in general... stable job, active social life. Things could be better if only she had Carl.

There is hope, however. Hope in the form of a voice which appears to Carl, then to Emily. That voice is Athena, but is she merely manipulating the situation, or is she genuinely attempting to help these two people? Life is messy, and she could be making things worse.
