Tavlin upon learning that Astarion was a vampire was, of course, horrified. he’s undead, he’s wrong, he’s wicked, and by decree of his goddess he should ram a stake through his heart. but he’s gotten to know Astarion, and he’s not really all those things. well sometimes he his, but Tavlin likes him well enough. Hard not to bond with the people sharing the same living nightmare as you. and also Tavlin hesitantly allows Astarion to drink from him, after all he is a cleric — a healer! — isn’t it his duty to help those in pain? after, he finds it incredibly thrilling, though he represses that feeling as best he can. In truth it’s a strange work around to intimacy. Though Astarion is exceptionally close, his lips against his neck, his body pushed against him, technically it is nothing more than feeding. He becomes a very willing subject to subdue Astarion’s thirst, though perhaps not the best choice; an underfed, iron-deficient elf is not a very amazing source of nutrition.
