Is Luka actually Klaus???

I hadn't thought of this possibility until Inna told me... Luka uses the same letters as Klaus... so it might be him posing as a warlock! in that case, the only witch would be the father making him look like a warlock and blocking Bonnie from noticing he's a vampire. Or else, Klaus has got witch powers too. The spoilers say that the originals can be absolutely anywhere! so wow they'll be surprised if Luka turns out being Klaus...

But I still hope he isn't! there would be much better men for the role!
