WARNING: If you don't want to know what happened in this episode, don't read this photo recap!
After Abigail broke the window to the church, all these ghosts just started appearing in the churchyard. Are they having a sit-in? Then the power in Port Moore goes out. Why? Presumably the dam that powers the town went kaput. The electricity was a major line of defense against the ghosts…so now, it’s open season.
The rest of Port Moore is similarly under siege by supernatural saboteurs. Doug gets accosted in jail, Carla thinks her husband is a ghost and tries to stab him, the place is crawling with creeps. The townspeople gather in the church for sanctuary — but with the electricity out, nowhere is a safe haven.
While Billy and his crack team of ghost hunters head up to the dam to try and restart it, and the electrical grid, those in the church are under attack. Luckily Paolo has his Venkman-style toy to blast them away.
Maggie transports Roman back in time to view the moment when Billy, Val, Doug, and Dan chased his mother out of town. Billy and Val allege she took advantage of their father; her story is that he had some bad stuff he wanted to get off his chest, which is why he engaged her services.
Roman confronts the gang on his mother. Father Dan comes clean: but qualifies that after they chased Roman's mother out of town, she was alive. They don't know how she died. Roman's finished being exploited for his powers, and leaves them in the turbine room.
The spectral Marcus comes back to taunt his mother, and bait her downstairs where the egg thing is. He pushes her into the mucous membrane, which looks strangely similar to the one on the tree where Abigail was trapped.
After he's finished with his mother, Marcus sneaks up on Dan, who's still guilt-ridden over the whole botched exorcism affair. Marcus makes sure the Father feels pain as much as he did. Looks pretty gnarly.
And, hope against hope, Billy manages to pry the last animal carcass free from the turbine blades and get it spinning again. Plus: free dinner! But before the electricity comes back on, the ghosts descend on Billy and Landis. And they think they're going to die. So they make out. Fortunately for them it was a false alarm.
