Okay so. I have been spending quite a lot of time working on my vampire protagonist dude lately, and I love him to death (ba-dum tss), so I think it's time to start really getting into his supporting cast: the vampire chick who turned him, and her slave boy thing who she really loves but would never openly admit it. Normally when I go into character development mode I just obsess over that particular character for, like, ever. The ideas for their history and their quirks and what makes them who they are just sort of come on their own, and then I'll follow whatever detail into the ground until it becomes something I like or I've exhausted all possibilities for it and find out it's dumb or doesn't work. It's important to me that these two characters get fleshed out, because Mr. Protagonist would be nothing without them. They're his family, they're close, and they interact almost daily, so they need to be people too. I have a freshly solid idea as to why Mrs. Vampire turned Mr. Pro, but there's a piece missing as to what has been holding them together all this time. Or why Mrs. V doesn't have more descendants (just Mr. Pro). Here are the things I know for sure: Why Mrs. V wanted to turn Mr. Pro into a vampire (but she hasn't told him, and may never) When it happened How it happened (oh god this was so fun to hack out) Mrs. V does have feelings, she just expresses them like a villain Here are the things I need to explore: Mrs. V and Mr. Pro's relationship (the entire timeline, including now -- at present they interact sort of like "friends who used to date." Sometimes she kisses him at work, but in my mind it's always been a selfish marking of territory. I have no idea how much she actually likes him or what message she's trying to send to observers) How Mr. Pro really feels about Mrs. V. Really. Mrs. V's actual relationship with her slave (they're pretty stiff in public, but I bet you that's just for appearances) Mr. Pro and slave's relationship. (Slave is much older, but Mr. Pro has free will. I feel like at some point they would talk about existential stuff, but the tone/purpose of the conversation is a mystery.) I am rapidly running out of brain fuel, so I'll try to wrap up with some coherence. Basically, I'm looking for techniques and methods that I might not have thought of for developing these characters. The obsess-for-weeks strategy is slow and subject to very many distractions (as well as being at the mercy of my muse, which is not always my friend)... So, what's your process? How might you go about sniffing out these details?
