I WILL NEVER GET TIRED OF VAMPIRE!SHANE. SO. HERE'S SOME PLATONIC NON-SHYAN VAMPIRE!SHANE STUFF BABYYYY
Shane got turned into a vampire at age 30-35 between the mid 1800's to early 1900's
There are a lot of Vampire!Shane aus where he's a pacifist and only drinks from animals or bloodbags but uh. Yeah. Ahem. This version is not a pacifist, he's a cocky and brutal vampire who truly loves the taste of blood and seeing his victims squirm, but he still feels remorse after the initial rush
When Ryan discovers Shane is a vampire, it's because he tried to attack him after being starved for months. Luckily, Ryan had holy water on hand left over from an investigation
Ryan gets super horrified of Shane, obviously. He views him as a scary, dangerous monster that only wants to hurt him and others
Shane is obviously DEVASTATED because his best friend just completely shut him out and kind of hates him now so he texts him nonstop trying to explain
Ryan doesn't even respond to these
So, next best thing, Shane shows up at his house
Ryan shuts the door in his face at first, but admittedly, he does miss his closest friend, so he opens the door with the chain still locked
While Shane does successfully convince Ryan that he's still Shane and doesn't want to hurt Ryan, Ryan isn't so convinced by his hesitancy to answer whether he's hurt other people
Eventually though, Ryan understands that it's survival over moral, and lets Shane in to forgive him
Eventually, the demon!Shane dynamic is up and at em, but of course, Shane is not quite a demon. Everytime their colleagues and friends would joke about Shane's alleged demonhood, they just look at eachother like 👀👀👁️👁️👁️👁️
Ryan over time tries to wean Shane off biting people and get him into bloodbags instead
Shane hates it but slowly gets into the habit of buying clean blood over hunting, just to make Ryan happy
It finally clicks for Ryan why Shane has such strange quirks like a love for Depression Era music, his odd vocabulary, and how he never seems to dress in the modern way
Shane will never hear the end of it about being a fake skeptic (because well, duh, then he'd be denying his own existence)
Ryan warms up to the existence of vampires enough to where he wants to be one, the thought of living forever isn't so bad after all
Ryan asks Shane to drink his blood (through his arm, of course. Let's keep this PG/platonic) or, in an alternate scenario, Ryan nearly dies and is bitten by Shane to save his life
They go on duel hunts together, and sometimes stick it out at home watching comedy movies to work off the urge to eat people when they can't afford to buy bloodbags
