Curate, connect, and discover
anyway here are all my “how did molly figure out he has blood hunter abilities” ideas
the obvious: he’s a sword juggler he had to have cut himself on accident at some point and then accidentally did a blood maledict on a nearby yasha or something
he got into a fight and muscle memory/instincts leftover from lucien took over
at some point he was like “whoever had this body before me had to have gotten all these scars for some reason” and activated his swords out of sheer curiosity
the best option: he was getting one of his tattoos and the artist drew blood and was also going over a painful spot and he freaked out and put Blood Curse of the Eyeless™ on them
