Who dat lmao?
but also, this was sort of a cop out to call on the spirits. Literally it's like getting the answers to the test handed to you.
No detective work needed whatsoever, just summon their spirits and BAM case closed.
But I guess you could argue that he had to "find" their spirits first,
but I still feel like it's such a boring way to solve a case just to ask the murdered guy who dunnit.
