This episode, the penultimate of both the season and the series, repeats a premise first used in S1 E3: twins, one alive one dead. The latter has issues with his brother, who is engaged to be married, and Melinda, whom he resents for having ushered his mother, a victim of the plane crash in S1, into the light.
But really, the episode is not so much about this. About the only original aspect of it is a new power for ghosts: the ability to appear as older than they really are. While the twin died at about 10, he takes on the appearance of his brother. ( See the Goofs section for the chronological problem in this.)
The real purpose of this episode is to set the stage for the final one. Mel's abilities are beginning to weaken, as the shadows take her over. Carl suggests she convince Aiden there are no ghosts. Or are the shadows actually doing it through him? The ghost's warning that she is in danger as he enters the Light solidifies this.
As my rating suggests, it's an average episode, typical of those from the last two seasons, when the new idea tank had run dry.
