wouldn't it be weird to kiss him because he thinks the guy is dead, I mean isn't that kinda like kissing a 400 year old dead body?

Nah if he actually thought that he's dead then there wouldn't be any point in saving him or protecting him for sunshine. He probably believes that the vampire is in coma or something like it. But true enough, it does seem like a well-preserved 400-year-old body since he reacts to nothing so...
Or maybe he just thirsty

can somebody tell me what this manages or if it is

maybe this is kinda random but I hope the brothers will get to think of each other like actual brother or will treat each other like ones.
dont worry everyone gets happy ending they have a little way to go so in the end there is happy end for two brothers and their lovers :)
