Thanks! Another page to add to the collection.
I wonder if there is a medical condition which accounts for Todd's blood being black, as opposed to red, or if this would be a continuity error.
There is a photo of a severed Wraith hand from Joe's own blog showing red blood (content warning: theatrical blood): https://i0.wp.com/josephmallozzi.com...013/01/199.jpg
This site states coughing up dark blood can indicate it came from the digestive system. Would that work for inactive* digestive systems too? https://www.nhs.uk/conditions/coughing-up-blood/
(*the adjective "inactive" is extrapolated from Keller saying in "Infection": "The treatment worked exactly like it was supposed to. It eliminated their feeding hands, activated their digestive systems...")
Addition: Nevertheless, existing on-screen visual evidence supersedes any scripts, filmed or not. "Runner" and "The Last Man" show red blood. Lorne shines a flashlight on a fallen runner hunter and Michael holds up a Queen's severed head in daylight. Wraith blood is red and and they are warm-blooded as per Todd's breath fogging up the glass in "Vegas."
