I have to say this and I would Amore to read people opinion about it.
now I know this is very late, but it bugged me since the end of S3A when the lunar eclipse made all the licantropi turn human for 15 mints. now I don't have a problem with that it makes sense in some way I don't even mind that it happened to Scott & Isaac.
I do however have a problem with that it also worked on Derek and here's why, now Scott & Isaac were BITTEN then turned into licantropi but they were humans at first. unlike Derek who was BOREN a werewolf it's in his genies, its in his DNA. no matter what Supernatural things happen nothing can change o alter the DNA o genies for 15 mints then go back to it's original status.
so that's my issue with the whole lunar eclipse
