I don't quite understand and can't fully conceptualize what will happen if lets say someone slashes off Klaus's arm...does it reform with the rest of its body...is it unable to be cut...cause that may be more reasonable and understandable.
the same goes for my second question...'decapitation' its listed as a weakness for ordinary vampires for example Caroline or Damon...and of course they die as a result. However does the same happen for an original...i highly doubt it because the are virtually immortal unless at the hands of the white oak stake.
its really not like their bodies are inpenetrable...take for example Klaus bites himself and uses his blood to cure werewolf bites...and the originals can be daggered...example the countless of times that Klaus has daggered his siblings...so what does happen really lets say someone were try to cut off an originals head...would it work...especially if they were desiccated..where it wouldbe more easily done.
answer to the question would be so greatly appreciated
