The premise was interesting. Melinda's husband has to leave a man behind in a building, then watch the building blow up. However, the interaction and 'tension' between the couple seemed fake or false.
What really stole the show was Melinda getting Joe Grimaldi to believe the man was his brother. Added to that, the scene in the hospital when Joe is pouring his heart out to his brother, only to find out the ghost isn't his brother is absolutely priceless.
Overall, the episode could have been better, but it could have been worse. It had a few moments worth watching, but watching the non-existent tension between Melinda and her husband was a little boring.
