I think they were trying to leave open the possibility that she was some horrifying ghoul under the veil, to keep it scary for viewers who are susceptible to that kind of thing,

I don't think that's right? He had just heard about Moriarty coming back to life. He decided to take drugs and meditate upon a hundred and twenty year old unsolved crime which revolved around somebody else apparently coming back to life in the hope it would give him some insight into the Moriarty case. He wanted to…

Given his past tendency to escape custody the second anyone makes a slight slip up in holding him, and the large number of innocent people he murders every time that happens, breaking his neck seems like a reasonable precaution.

Compared to Buffy/Angel, it's not as funny, and has fewer fights.

Controlling three galaxies = literally 100,000,000,000s of star systems. In order to expand that fast they'd need to adapt their 'Grunt' technology for exponential growth…

Somehow Jason always seems to lead people down the satanism path.

Was it supposed to be just a coincidence that one part of the plot was set in a place called Truth or Consequences, and that was also what was written in the Osgood boxes?
