Why did Sara and the others suddenly leave?
If i remember correctly, sometime after the "Day-O" scene Lydia comes downstairs having failed to get the ghosts to make an appearance. She says something about them not wanting to be teased or made to do stupid tricks. Delia says "They're dead, it's a little late to be neurotic".
Then suddenly Sara hands Delia the pictures, looking totally done. As is everyone else apparently cause they're all leaving. Delia says "this was not a hallucination" and that what happened was real, etc. Delia's agent insults her art (tasteless asshole) and they're gone.
What happened here? Firstly, why did they leave? Second, nobody said anything about a hallucination. Why did Delia say that? Is that the writer's way of informing us that they don't believe what happened anymore? Why wouldn't they?
This is so disjointed. It's like they skipped a scene or something. It'd make more sense if you heard Tim Burton in the background saying "Maree, it's time to leave. Catherine, argue at them like they're skeptical now. And....cut".
