Let’s say Klaus sires vampires or hybrids again, will this result in an intact sire link or will they too have a broken link to him like his former sireline has?
Unfortunately he’s dead so he can’t. He could have stared a new line after the break, but he didn’t. He did add to Hope’s line by creating hybrids with her blood.
I think he could have done it. It wouldn’t make sense Magic-wise for the new vampires otherwise, because what keeps them around is the connection to Esther’s original spell
