That's a good point about Klaus killing, or atleast being responsible for the death of Caroline. I don't think he would care if he killed Tyler, but he does seem to have real feeling for Caroline, and his guilt for her death could be what motivates his departure from Mystic Falls and his journey towards redemption.

Thanks Obro, in my opinion if the writers wanted to kill of Klaus,they ought to have done it in season 3 and left rebekka to be the sire 'parent' of  Katherine, Salvators and Elena ..and her seeking for the cure this season would bring incredible sub plots of who would support her to do so(Elena,Stefan,Caroline) and who would try to dicorage her from it(Damon,Katherine maybe Elijah as the last original out of brotherly love).However as it stands now that Klaus is still in the picture there is no better way but to leave his werwolf side as the loophole for keeping the mystic falls vampires as they are while giving him an indefinite exit while retaining him an ever present menace seeking vengeance at some future point.In any case being a werwolf for Klaus is simply a stay of execution but it is a death sentence.

Ok having seen the new episode I am starting to think that it is less likely that Klaus will be cured, given that there is only one cure and Silas is some big bad that has to be killed.

This is soo Angel (BTVS) a redemption story 

It is possible with the new series that Klaus could be cured but the vampires in his line are kept the same. If Klaus is cured that means he would go back to just being a werewolf bound by the full moon. It would explain Hayley's part in the show, helping thourgh the curse. Reading the speculation about Klaus attemtping to re-curse himself back into a vampire is an intriguing notion, that is if the show goes in the direction of making just a werewolf. There is nothing more humbling that having to turn into a wolf on every full moon. I am excited to find out what happens next

@ Lynx81...sure man! Yeah..Klaus as an ordinary werewolf would be putting a huge bullseye on back! Considering he has many enemies and that as wolf,he would be pretty vulnerable against them..

^ I like your theory as  well! It would be interesting to see Klaus trying to turn himself back into an Original Vampire after being cured,cause if he was just a new born vampire/werewolf hybrid..he would still be weak and vulnerable against his enemies

Katherine has the cure knowing her and her sneaky ways she'll use it before they get it.Just don't know on who she'd use it probably klaus because she had to flee town over him.

The big debate that my friends and I are having about curing Klaus is whether or not it will also cure his line of vampires. Understandably killing an original vampire will also kill his line but I am not sure if that is true for the cure. One of the ideas I have heard in regards to the spinoff with Klaus is that he will be cured and he will seek redemption in New Orleans and the catalist of the his redemption will come from him no longer being a vampire but simpy a werewolf that is bound to the curse. I think that is great concept to start the new show with but in doing so he may just cure his own line, which is every main character on the show. Only time will tell

If Klaus is cured I don't think his entire bloodline would be cured, because then they might as well change the show to The Diaries, since everyone will be human again.

I also highly doubt the cure would do anything to Klaus's line (though I still wonder why Klaus had Kol kill Mary Porter just so they would learn of her bloodline; could Klaus and Kol be covering something up--the reasoning behind why Klaus would wish to hide this fact is bizarre almost like a writing error OR future plot device; if anything I'd think he'd want to prove his bloodline tie without a doubt...taking away their options) other than severing it's ties and origins. It will now be making a truly powerful and "here to stay" type of vampire lineage... A new species, in much the same way the original werewolves (or regular werewolves like the TV series, who may be a species and not born of a mystical disease) are, with there origins being cloudy and going back as far as human history and memory has existed...in any form.

It wouldn't surprise me that Katherine would not only ram the cure down his throat (or hit him with an injection dart--easy stuff), but possibly NOT kill him as she knows he has enemies from here to the moon... He killed her entire family, was going to sacrifice her, forced her to sacrifice her humanity, and perhaps along with that last curse lose the love of HER life because he doesn't seem to love vampires as much as he does a human... She loathes him. More than anyone else, I think. Leaving him alive let's him suffer far more than a death after realizing, just barely what he has lost. She might want it to sink in, for a long time to come. So I think the topic is dead on, Klaus WILL be a target. I do hope he makes it into the new series as you guess, it would be nice.

This series is about vampires, so the other while having witches a few vampires and miscellaneous things, I think it may focus on werewolves instead. Perhaps it will be in that series were we finally meet the original pack? If it is werewolves with humans, much like a mirror of the Vampire Diaries, then they'll certainly be there eventually.

We'll see what happens with Tyler as well as he is the only hybrid on the planet left alive. With that fact also means that if Klaus is taken a notch down, there will be no more anti-werewolf venom cure-all. They of course never did try drinking the blood of another hybrid, perhaps Tyler's works as well...Klaus is known to be selfish and a liar.

Should be promising if they do this new series right, but I think Klaus's days as an original hybrid are soon drawing near to a close...
