guillermo is such a memorable character, and I think that’s because in the first episode - and by all conventions of the story - Guillermo is set up to be the everyman. hes the human living amongst vampires, he gets to correct them when they’re not acting “human” and does the menial tasks that we all watching, unfortunately, have to do. hes Normal. he doesnt fly or become a bat, so he has to take the bus. he used to work at panera bread. he goes out to meet people at events, like LARPing. but then theres also this dissonant layer - at vampires only events guillermo is literally kept in the dingiest rooms with the other familiars because hes not allowed in; guillermo now willingly works as a slave for vampires and has done so for 10+ years (even the term “familiar” is usually associated with animal companions); guillermo goes to those events to source humans for his boss and his boss’ roommates to eat, which means guillermo has spent over a decade complicit in murdering people because he also wants to be a vampire. guillermo is first shown to us (by the somewhat biased/limited documentarians) to be a naive, optimistic man, and once hes able to assert himself and his own feelings he quickly reveals that hes just as batshit as the rest of them, he just hides it better.
