Does your character have blood?: Yep.
Would their blood smell better or worse based on that Affinity: Probably lean worse, especially with recent events. He's starting to get more confident and ready to Do Stuff thanks to powers, and he would occasionally fall into his "I wasted my whole life what do I even do now" hole... if he hadn't broken his heart stone and accidentally erased his biggest regrets from memory. Maybe he'll get that stuff back at some point but time will tell.
Any other notable facts about their blood: MIDICHLORIANS???
