Does your character have blood?: Yes!
Would their blood smell better or worse based on that Affinity: Arguably better just based on affinity; he's a very driven person but he's also very Done and sort of reaching the point of "fuck it"-induced zen.
Any other notable facts about their blood: ...all of the above aside his blood is full of zombie plague and it'll definitely taste more like blood that's been dead for a while. and that's fucking disgusting. don't put it in your mouth, elda. oh my god.
