Can you figure out this week's Secret Themes?

Each group of 10 otherwise unrelated questions has a theme running through their answers. Can you answer the questions and figure out the theme? Answers will be posted in a few days. This week both Secret Themes were Halloween-related, although the component answers to each round were not. I accidently used the round I thought would've been better for the Ray's teams at Frank's and vice versa. Oops...
