Allison is more than a little dubious when the ghost of FBI Agent Cooper appears in her kitchen with information on the long unsolved murders by a serial killer known as the Gentleman Caller. The information turns out to be accurate and suddenly Cooper's back with information about another case.

At work, Joe comes under a lot of pressure to hire an engineer who's made very valuable suggestions on Joe's project.

Reunited And It DOESN'T Feel So Good...
26 March 2009 | by cchaseSee all my reviews

Alison has faced some pretty dark characters from "the other side" before, and some have even made return appearances. But none of them like the 'late' FBI profiler and part-time vigilante serial killer Edward Cooper (Kurtwood Smith), who just can't seem to get enough of our favorite medium...a sentiment she most certainly does NOT share.

Cooper's return is heralded by one of Alison's trademark disturbing visions - this time a slaughter at a roadside diner, by a man distraught after being jilted by a waitress who works there. Awake and online trying to find evidence of the massacre, she's met with something even less comforting...the presence of Cooper, who's there to make her a deal, no strings attached. He wants to strike up an 'alliance' with Alison that involves using his newfound 'insight' in the after-life to provide her with information about dangerous criminals the police have been trying to catch with no success. Of course, Alison's no fool...With a deal like this, especially when you're talking about Cooper, there are ALWAYS "strings attached"...and the catch to this little arrangement is a doozy.

On a side note, when Joe is saddled with a completely unlikable and untrustworthy new employee he's pressed into hiring by his new boss/business partner, it's Ariel's blossoming gifts that come to his rescue to help him solve the conundrum of how to get rid of him.

If only 'Mom' had it so easy. Once again with another excellent performance by Smith, this episode proves why vigilante justice, even in the guise of saving lives and gaining retribution for victims, only succeeds in making more victims out of people who are innocent, and results in the end with justice being found for no one.
