At first, everything about them sounded plain ridiculous, but as I think about it more, I start liking the idea, as it also occurred to me once, this witch/vampire hybrid-thing. Although, I never thought they would actually make it real in TVD Universe, heh. But apparently, they did. Anyway, so, whether or not Kai turns into one of them, I don't know if that would be a good thing or a bad thing. I mean, first of all: How is he going to turn If they want him to be one of them? In order for him to turn into a vampire, he'll have to die. Thus meaning all of his Coven dies with him, BUT! What If this witch species, or I should better say, HIS WITCHY MALFUNCTION won't allow him to stay dead for more than a few minutes.. As, what if. . he could immediately siphon the vampirism magic within his body right after the moment he died? And he just wake up a vampire with witch powers? I mean. . I was thinking back in Season 3 If I am not mistaken, when they wanted to kill Klaus, but then they found out that If an Original dies, then all of his progeny dies. And then they killed Finn, and after that, but NOT RIGHT AWAY, Sage died, because Sage was his progeny, he turned her a long time ago, they were lovers, blah, blah. Anyway, my point is, what If the rest of the Gemini coven won't die immediately when Kai drops dead in order to complete the process? I don't know. <.> It got me very confused, heh. xD
